Hey guys, that tutorial was awesome, my flash is booting at almost all computers, but I thing there's some problem with grub4dos or mbr record. On computers where it works is showing before going to grub message like "Try hd(0,0) fat32" and then grub normaly shows up. But on some computers it doesn't and jump right to WinPE or grub on HDD for instaled OS. Don't you know where is problem? Maybe i'll try ext2 partition and normal linux grub but i'd rather like this "all in one partiotion" solution.

I get that too sometimes, however, on the machines i did get that on, i have designed a slightly updated version of Si's guide.

Install pendrivelinux USB software to the drive. This uses syslinux as the boot method and then chainloads GRUB. So you can still do your menu.lst entries in the same way, but your actually using syslinux as the boot peramiter for the USB.

The good thing about this method also, is that you can then boot .iso files too instead of having them extracted to the drive.

No problem, i wasnt very clear in my post.

You need to download and run the following file:

http://www.pendrivelinux.com/downloads/MultiBootISOs/MultiBootISOs.exe

This will install syslinux to your USB drives boot sector and then try booting from the USB device on one of the machines that didnt work before. It should now work (possibly).

Let us know if it worked or not and we can try other things if need be.

I was working on same thing manualy but this utility is more comfortable. I tried to boot and now it boots ok to syslinux, then chainloads to grub.exe, but promlem is that grub is looking for menu.lst everywhere and it take grub from hdd, so I have to try google something to change it.. if you have and idea, pls tell me.

It's weird because that usb with grub shoud be hd(0,0) in that moment and grub should look at usb first but it tooks menu.lst from hdd..

Sounds like the Syslinux config file is set incorrectly. Ensure that THAT one has the correct perameters.

Otherwise, my only other suggestion would be to wipe the USB device, install that application and THEN install all your menu.lst perams etc.

syslinux IMHO set correctly because it loads grub.exe.. but grub.exe doesn't load menu.lst from flash.. sounds like computer does'n see usb as hd(0,0).. i'll try wipe that flash.

Let me know if that worked.

It may be that you have to set the exact file locations in syslinux. So instead of just simply calling grub.exe in syslinux, maybe actually tell it to call and use grub.exe on a usb location of hd(0,0)?

I tried to wipe usb but it didn't help.. So its' workning only on some computers.. maybe some day when i will have time a'll try one linux partition for grub and fat32 partition for data

To be completely honest... I still find some work with mine and others dont... There doesnt sto be any rhym or reason to it...

I have spend the past few days searching around for ways to get this working and now have a completely new USB stick of tools. However, i no longer use Grub4dos, but Grub itself. Plus, i dont ahve ANY extracted .ISO files on the device any more. I ahve all the .ISOs in one folder and boot the .ISOs directly by mapping through grub.

I find this is, for one thing, tidier on the key and easier\les confusing than the old method in your tutorial.

For that reason, would you mind if i wrote a new guide on this, using the mothod to use Grub and boot the .isos directly?

Please do tell! That's like the holy grail or something :D

    • Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know

      Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know The ONLY thing I need to know is the price, which I know will be way higher than I (and most people) are willing to pay for a phone... so basically nothing here I need to know. PS: Nice job getting that Apple reference to a non-existent and unrevealed product as "competition" in there. Cheque is in the mail.

      Well I really think the repasting helped if your higher clocks have returned, maybe the next thing to look at is if there is a problem with your case airflow? I guess this because your 3080 has returned to optimal state, but is still staying too warm, which might suggest it was thermal throttling before you repasted, of which the only logical conclusion could be outside factors.

    • Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know

      Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know by Hamid Ganji Galaxy Z Fold 7 - Image via Samsung The next generation of Samsung foldables is set to be unveiled next month at the second Unpacked event of the year. Samsung’s 2026 foldables are not expected to offer significant upgrades over their predecessors, with the Korean firm instead focusing on design refinements and conventional upgrades such as faster processors and better cameras. However, Samsung is reportedly planning to unveil an all-new passport-style foldable this year to rival Apple’s first foldable iPhone, which is expected to debut this September. Here’s a roundup of everything we know about Samsung’s upcoming foldable devices ahead of their official debut. When can we expect Samsung’s new foldables? The Galaxy Z Fold 7 and Z Flip 7 series were unveiled in July, and Samsung is expected to maintain this timeframe in 2026. Based on previous reports from Korean sources, Samsung will hold its Unpacked event on July 22 in London, UK, to pull back the curtain on the Galaxy Z Fold 8 series. The devices are also expected to hit the shelves a few weeks after launch. However, Samsung has yet to announce an official date. A new naming scheme? One of the most interesting changes we might see this year is a new naming scheme for Samsung’s latest foldables. SamMobile reported that since Samsung is expected to unveil three foldables this year, it has adopted a new naming strategy to simplify product identification for customers. Accordingly, the standard Galaxy Z Fold 8 will reportedly be called the Galaxy Z Fold 8 Ultra and will serve as the direct successor to last year’s Galaxy Z Fold 7. The “Ultra” suffix suggests the phone could feature higher-end specifications, such as additional rear camera modules. Samsung’s new passport-style foldable is expected to carry the Galaxy Z Fold 8 name without any suffix. This model is reportedly equipped with two rear cameras. No major changes are expected for the Flip model. Galaxy Z Fold 8 Ultra and Z Flip 8 anticipated specs Rumors over the past few months suggest Samsung is preparing several upgrades for its upcoming foldables, although the devices may continue to rely on larger batteries and faster charging speeds rather than dramatic design changes. The primary focus this year is expected to be the Galaxy Z Fold 8 and its wide-screen design. Galaxy Z Fold 8 Ultra official CAD renders - Image via AndroidHeadlines Here are the anticipated specifications for the Galaxy Z Fold 8 Ultra based on previous leaks: 6.5-inch outer display and 8-inch inner display, 120Hz refresh rate, and 2,600 nits peak brightness Snapdragon 8 Elite Gen 5 processor, paired with 12GB or 16GB of RAM and 256GB, 512GB, or 1TB of storage 4.1mm thickness when unfolded and a weight of 210g 200MP main camera, 50MP ultrawide camera, 10MP or 12MP telephoto camera, 10MP cover camera, and 10MP selfie camera 5,000mAh battery with 45W wired charging Android 17 and One UI 9 As for the Galaxy Z Flip 8, the device is not expected to be a major departure from its predecessor, although it could become slightly slimmer. Expected specifications include: Snapdragon 8 Elite Gen 5 or Exynos 2600 processor 12GB of RAM with 256GB and 512GB storage options 6.9-inch Dynamic AMOLED 2X inner dispaly and 4.1-inch Super AMOLED outer dispaly 50MP main camera, 12MP ultrawide camera, and 10MP selfie camera 4,300mAh battery with 25W wired charging Android 17 and One UI 9 Samsung’s foldables are also expected to launch with Gemini Intelligence, Google’s AI suite for automating tasks in Android ecosystem. Moreover, given current memory and component costs, some Galaxy Z Fold 8 Ultra and Z Flip 8 variants could see a price hike. Galaxy Z Fold 8 adopts a wide-screen design The centerpiece of the upcoming Unpacked event could be the Galaxy Z Fold 8, previously rumored as the Galaxy Z Fold Wide. This model adopts a passport-style form factor and is expected to compete directly with Apple’s iPhone Fold. Galaxy Z Fold 8 official CAD renders - Image via AndroidHeadlines Here’s what to expect: 7.6-inch primary OLED display and 5.4-inch cover display, 120Hz refresh rate, 2,600 nits peak brightness, and 4:3 aspect ratio Snapdragon 8 Elite Gen 5 processor, 12GB or 16GB of RAM, and 256GB, 512GB, or 1TB storage options 4,800mAh battery with 45W wired charging 50MP main camera, 50MP ultrawide camera, and 10MP selfie camera Android 17 and One UI 9 The three new foldable phones are unlikely to be the only devices unveiled at Samsung’s Unpacked event. The company is also expected to introduce the Galaxy Watch Ultra 2 and the Galaxy Watch 9 series.
