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 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

    • NirLauncher 1.30.24

      By Copernic · Posted

      NirLauncher 1.30.24 by Razvan Serea NirLauncher is a suite of more than 200 of NirSoft's excellent portable freeware Windows utilities, and provides an interface that makes it easy to find and launch the tools you need. Which works for us - because there's something here for everyone. Have you forgotten a password stored in your browser or email client, for instance? Recovery tools here may be able to find them for you. Maybe you'd like to check your hard drive health? A disk tool will display its S.M.A.R.T. data (if the drive supports this), so you can view read/ write errors, temperature and other useful details. Is your system unstable? The System Utilities section includes several tools that can help to explain why your PC might be crashing. And there are a host of other programs on offer in categories like "Network Monitoring", "Web Browser Tools", "Video/ Audio Related Utilities", "Outlook/ Office Utilities" and more. Please note, perhaps because a few of these tools can be used maliciously (the password revealers, say), some antivirus programs will flag them as threats. We've never had a problem with any NirSoft tool, though, and you can read more on this issue at the author's site. NirLauncher is an excellent set of free tools, and a must-have for everyone's portable troubleshooting toolkit. NirLauncher Features: NirLauncher can be used from USB flash drive without need of any installation. NirLauncher and all the utilities in the package are completely freeware, without any Spyware/Adware/Malware. This package doesn't contain any 3-party software, toolbars, Web browser plugins, or other unwanted surprises. It will not install any software on your system and it will not change your Web browser homepage or other settings on your system. NirLauncher package includes variety of tools that you may need for your daily computer use, including utilities to recover lost passwords, to monitor your network, to view and extract cookies, cache, and other information stored by your Web browser, to search files in your system, and more... For every utility in the package, you can easily run it, view the help file, or jump to the Web page of the utility. When using it from USB flash drive, the configuration of every utility is saved into .cfg file on the flash drive. On x64 systems, NirLauncher automatically run the x64 version of the utility, when there is a separated x64 version. NirLauncher also allows to add more software packages in additional to the main NirSoft package. NirLauncher allows you generate plugin files for BartPE (Launcher -> Generate BartPE Plugin Files), so you can easily use the utilities of NirSoft from a bootable live windows CD. Additional packages (Piriform, SysInternals...) and instructions are available on the Nirlauncher download page. Note: This zip file below is password-protected.

    • Euro-Office must default to ODF to be considered "genuinely European", LibreOffice argues

      By MikeK13 · Posted

      What people who support this position of LibreOffice do not understand is that EuroOffice is not made to appease the open source enthusiasts (I am also one) and evangelists. EuroOffice was made because some European companies wanted independence from Microsoft Office Suite, which is something installable on your computer. This move to independence was pushed by public institutions and governments in Europe, as well. Using a proprietary FORMAT as default, does not make you dependent on MS. The actual program does. A format can be changed with a simple update in the future in a dystopian world where MS would manipulate the format to lock others out. However, using MS Office proprietary format, guarantees that all the current documents used by companies, organizations, institutions, etc, will be compatible with EuroOffice and the suite will have the best chances at adoption, especially by slow moving organizations like governments and the public sector. It is as simple as that. For the same reason, even the UI is incredibly similar to MS Office. For the same reason (adoption) the choice was made to be open source. Not because EU particularly loves open source ideologically, but because it gives the best starting point to create trust in the project and amass developers and contributions to the project quickly, to catch up with proprietary projects like MS Office. I don't understand how people don't realize it.
    • Microsoft hides these secret Windows 11 performance boost settings available on every PC

      By WaltC · Posted

      How old is this tip? Seems 15-20 years old? Processor states for the CPU under Windows power options has been a thing for a long, long time. It certainly isn't new or hidden... Also, with laptops it doesn't make any difference what OS you are running, all of them are configured for battery longevity over performance, for obvious reasons. Wanted to add as well that most systems in use currently do burst as setup in the uefi bios settings, and usually when a setting is "hidden" like this in Windows it's because it's either obsolete or it is redundant--doesn't override the bios and the CPU drivers. There is a lot of crap in the registry that needs to come out...;) It's hamless and might consume 1-2kb of space in total, though.
