Why did you run testdisk? It is designed to recover your partition table. By virtue of the fact that Ubuntu still boots from the same hard disk, the partition table is probably OK. Even if it wasn't, you should NEVER use testdisk to modify the partition table on your system disk! Can you elaborate on why Vista is not booting? It might be more productive if we started this discussion from there.

Might run Fix BOOT from Vista command prompt:

Nevermind , that's gone from Vista -- probably need to do a Repair install of Vista.

Save, back-up important personal files first.

In order to start the Windows Recovery Environment you must boot your computer off of the Windows Vista DVD that you purchased or that came with your computer. To start this process, insert the Vista DVD into your DVD drive and turn your computer on. Your computer will start and you should see your BIOS listing your hardware and other information.

The Windows Vista disc can fix a lot of startup issues. Though honestly it's not clear what the problem is on your end, you haven't mentioned any errors, or even what happens when you attempt to start Windows on your computer.

The Testdisk output seems to indicate that all your partitions are there, but like xorangekiller mentioned you probably don't need Testdisk unless you specifically have an issue with your partitions(s) or need to recover data off the hard drive.

I ran Testdisk because I thought there might be a problem with the Windows partition on the hard disk (I'm a novice). I get different behavior when I try to boot Vista. Sometimes I'm forced into a chkdsk that never finishes. Other times, the desktop loads, but if I click anything, the machine just hangs. I have to force shutdown with the power button.

Vista came already installed on the computer and I don't have a repair disk.

Not much you can do then.

I think it's clear that your Vista partition is messed up.

Maybe you can borrow a Vista dvd from someone to repair it.

I don't know if something like Partition Magic would help.

It sounds like your hard drive may be developing problems. Is Ubuntu installed on the same hard drive or a different one? If its on the same one, is it slow to boot or does it report any disk I/O errors?

In Ubuntu, open Disk Utility, select your hard disk, and click "SMART Data". That should tell you whether the hard drive is physically having problems (most likely developing bad sectors by your description), or the issue lies elsewhere. Particularly pay attention to the "Read Error Rate", "Reallocated Sector Count", "Seek Error Rate", and "Current Pending Sector Count". Those are the most likely attributes to indicate a problem. DON'T GO BY THE OVERALL ASSESSMENT! It will often say "Disk is Healthy" unless your disk is in VERY bad shape.

Also, testdisk is an expert tool. You definitely shouldn't be using it if you're not sure EXACTLY what you're doing. While it can be used to recover from complex failures, it can also very easily be used to cause damage that is difficult to repair.

You're right Hum; I forgot the OP said it is a laptop. He may have two hard disks in his laptop, but its very unlikely. I should have assumed that Ubuntu is installed on the same disk as Vista. Consider my previous post amended accordingly. (I can't edit it anymore.) My main point and instructions are still valid, though. In context, its a fairly trivial detail.

Bad sectors are "reparable" in some cases. Your hard disk has a reserved area where a very small number of sectors can be remapped. However, if a sector cannot be remapped, either because the reserved space is full or for some other reason, then its time to backup your data and get a new hard drive.

Try running HDAT2 to repair the bad sector. After it completes, reboot back into Ubuntu and check the "Current Pending Sector Count" in Disk Utility again. If it has dropped to zero, make sure there are no other errors reported by SMART, and try starting Vista again. Even if all the bad sectors have been repaired, its likely you will have to run chkdsk on your Windows partition before it will boot.

Thanks for your help! Here's the result of Disk Utility...looks like bad sectors. Is this the end for my laptop? Will the Ubuntu side die eventually too?

You should really back up your data ASAP. The more you use the laptop the more bad sectors you're going to get.

Back up the data onto a USB drive or something similar. Ubuntu & everything else on the hard drive will eventually be unreadable.

The laptop itself is fine, you'll just need to have a new hard drive installed & then re-install Windows/Ubuntu from scratch.

It is definitely a good idea to backup your important data - which you should be doing regularly anyway - but a couple of bad sectors does not automatically mean the end of your hard disk. It is sometimes possible to remap bad sectors and for the disk to be completely usable for years after. However, the fact that your disk somehow developed bad sectors does make it more likely that you will get more, even if the ones you have can be remapped. If this is your primary computer, I would recommend preemptively ordering a new hard drive for it. Otherwise if you don't rely on it every day, I would wait to see if the sectors can be remapped before ordering a new disk.

    • Micron reveals AI companies are spending billions to lock up its memory years in advance

      By Karthik Mudaliar · Posted

      Micron reveals AI companies are spending billions to lock up its memory years in advance by Karthik Mudaliar The demand for more memory is far from over, and Micron is turning the AI-driven memory shortage into a much more predictable business. The company has revealed that it has signed 16 strategic supply agreements backed by roughly $22 billion in customer deposits and other financial commitments. The contracts cover DRAM and NAND deliveries over several years, with some running through 2030. With the AI boom, demand for high-bandwidth memory (HBM) has grown so quickly that large customers are now prepared to help finance future production in exchange for a guaranteed supply. According to Micron’s latest financial results, the company received commitments worth about $22 billion across its new agreements. Around $18 billion is expected to arrive as cash deposits, while the rest will come through other financial arrangements. Micron says the agreements could generate approximately $100 billion in future contracted obligations. They cover around 20% of its expected DRAM shipments and one-third of its NAND shipments during their respective terms. It should be noted that although AI infrastructure is the main force behind the current shortage, not all 16 agreements with Micron involve AI companies. Micron said the customers also include consumer electronics and automotive businesses, two sectors that increasingly compete with data centers for the same manufacturing capacity. HBM is consuming an increasing share of that supply. Unlike conventional desktop or server RAM, HBM stacks multiple memory dies vertically and places them close to an AI accelerator. This gives GPUs and other AI chips access to data at much higher speeds, but it also requires more complicated manufacturing and packaging. Micron says its 12-layer HBM4 memory is now shipping in high volume for a lead customer, with samples also supplied to other companies. The chipmaker has already generated more than $1 billion in HBM4 revenue and says the product is ramping twice as quickly as its earlier HBM3E generation. Samsung has similarly warned that the memory shortage could continue into 2027 and beyond. Consumer memory companies have also had to address sharp increases in DDR5 pricing, suggesting the effects are already reaching beyond the data center. For consumers, that could mean the AI memory crunch lasts longer than expected, even as manufacturers invest heavily in new production.

    • Microsoft updates Visual Studio Code with chat cost tracking and multi-agent chats

      By zikalify · Posted

      Microsoft updates Visual Studio Code with chat cost tracking and multi-agent chats by Paul Hill Microsoft has just launched Visual Studio Code 1.126, its latest weekly release. This time, the company has focused on letting you see the total cost of chat sessions to spot expensive conversations; enabling multiple chats per session that run side-by-side in one agent host Copilot session; and letting you browse new folders safely in restricted mode. We have now reached the stage where free AI in IDEs is coming to an end. To help you keep track of your costs, VS Code now lets you see the entire cost of a chat session, rather than just individual turns. This should give you more transparency about which sessions consume the most credits, so you can better manage your usage over time and spend less. For those of you using the Agents window, you know it is possible to run and manage multiple agent sessions at once. In this update, a Copilot session started from an agent host can hold several chats at once. Explaining how this feature works, Microsoft writes: Finally, from this update forward, Microsoft will remove the pop-up when opening an untrusted folder. When you open a new folder now, it will automatically open in Restricted Mode. You will see a banner that lets you manage the trust level of the folder. Microsoft has made this change so that it’s easier to start inspecting code without giving it trust right away. If you have VS Code, you can check for updates within the app now to get this new version. Otherwise, you can download it from the Visual Studio Code website.
    • Anthropic accuses Alibaba of using 25,000 fake accounts to copy Claude's capabilities

      By Karthik Mudaliar · Posted

      Anthropic accuses Alibaba of using 25,000 fake accounts to copy Claude's capabilities by Karthik Mudaliar Anthropic has accused Alibaba of using nearly 25,000 fraudulent accounts to extract capabilities from Claude on a huge scale. According to a report from Reuters, Anthropic told US lawmakers that operators linked to Alibaba and the company’s Qwen AI team generated 28.8 million exchanges with Claude between April 22 and June 5, 2026. That is a lot of Claude conversations, but Anthropic says this was not ordinary chatbot use. The company believes the accounts were part of a coordinated effort to collect answers that could help train or improve rival AI systems. The alleged campaign reportedly focused on some of Claude’s most valuable skills, including software development, multi-step reasoning, and agentic tasks. In practical terms, that means getting an AI model to plan and complete work across several stages rather than simply answering a single question. This is called 'distillation,' where AI companies use outputs from a larger model to train a smaller and cheaper one. The smaller model learns to imitate useful parts of the more capable system without needing the same amount of computing power. The distillation process isn't automatically suspicious, but the problem comes when one company gathers another provider's outputs without permission and at an industrial scale. Also, this does not mean Alibaba obtained Claude’s source code, model weights, or original training data. Instead, Anthropic claims the accounts repeatedly asked Claude carefully designed questions and collected the answers. Those answers could then be used as training material for another model. Anthropic has made similar accusations against DeepSeek, Moonshot AI, and MiniMax earlier this year. As Neowin previously reported, Anthropic said those three companies collectively generated more than 16 million Claude exchanges through roughly 24,000 accounts. Anthropic says the new campaign produced almost twice as many exchanges in a matter of weeks. Anthropic reportedly told lawmakers that the campaign could help Chinese AI developers approach the capabilities of its Mythos Preview model. Mythos is focused on advanced cybersecurity work, including finding and exploiting complex software vulnerabilities. via Reuters | Photo via DepositPhotos.com
