Help newbe struggling to get Ubuntu back after Xp install. When I install the grub fix program and select Unetbootin I get "Windows cannot start..... cannot read from selected boot disk."
Xp boots ok if I select it.
here is my drive info
sda1 boot ntfs
sda5 Linux Swap/Solaris
sdb sdb1 boot ntfs
I do not see the Linux partition for Ubuntu. Maybe I lost it when I installed XP. So if I re-install Ubuntu will I still have XP or do I need to start over... installing each OS to its own drive with the other one disconnected?

hey I need some help.
I have had an error within vista that has caused my dvd rom to bonk out on me.
I have fully installed and updated windows vista on a separate partition using a flash drive.
I then ran unetbootin to fix the grub install, only to have it wipe out the vista boot ability all I get is a /boot/bcd error.
I have tried to find a way to fix the error within /media/boot/bcd from within ubuntu as thats all I have working now. But no luck.
Can anyone help here? with no DVD drive I have no way I can find to fix this within ubuntu.
And to make matters worse, booting with a USB drive wont run the repair feature. I dont know why.

I am using a Aspire One with Windows 7 and Ubuntu 9.10. I guess something happened to my grub menu file and now it wont boot. It just boots to the grub command prompt. I tried to use the above method to make a bootable SD card so that I can install Super Grub Disk and fix it, but no matter what I install on any card and boot from it on my computer it throws the prompt:
BOOTMGR is missing
Press Ctrl+Alt+Del to restart
What now? Anyone know why it is doing this? I installed 9.04 just fine with this program and same setup before with no problems
Note: I am using the Windows version of UNetbootin from my wife's Windows 7 Aspire One.

I found a sgd file that was an executable and was about 5mb in size. Do i just use UNetbootin to boot with this like i would with any linux distro? My use of this would be to fix the boot grub after i wipe win7 partition and install xp on it; so i would then be able to boot xp and ubuntu without wiping all and starting over again.
SGD will repair the grub?
http://supergrubdisk.org/ ? That's actually an older, customized build of UNetbootin I built, that has the Super Grub Disk floppy disk image embedded inside, so you don't have to separately download it. You should be able to simply run the executable and follow the instructions at http://www.supergrubdisk.org/wiki/AutoSuperGrubDisk
However, if you're simply following the instructions I have in my post, you will not need the Auto Super Grub Disk executable file; it will automatically download the latest Super Grub Disk floppy disk image file for you and use it.
So I have 7 and ubuntu now. And once if i do...get rid of 7 and put xp on my netbook; I just need to follow your instructions and then i'll repair the boot menu and be able to boot xp and ubuntu once again? I have UNetbootin too; that's what i use to boot all my distros. It has only failed on stuff like baktrak and anonymos os. Other than that its a lifesaver!!
Thanks for the step by step very nicely explained how to, was very helpful to me.
