Locked out of Windows Partition with Grub

[coffeecat]

Haha yes I should have mentioned that I'm running Grub 2.

It was always clear that you were running grub2. The fact that you had set up entries in 40_custom and had disabled 30_os-prober was relevant to the advice given, and would have helped if you had mentioned it. Disabling os-prober means that update-grub no longer autoupdates grub menu entries for other OSs. Using 30_os-prober is easier because it will detect the new UUID and sort everything out for you. Using 40_custom, you have to change the UUID yourself. There's no need to post your 40_custom - grub.cfg in your boot script output makes clear what is in it.

Instead of this stanza:

menuentry "Windows XP Ultimate" {
	insmod ntfs
	set root=(hd0,2)
	drivemap -s (hd0) ${root}
	chainloader +1
}

This should do the trick:

menuentry "Windows XP Ultimate" {
	insmod ntfs
	set root=(hd0,2)
	search --no-floppy --fs-uuid --set 2e3857fb8cc54bfb
	chainloader +1
}

One other thing to note. You have this is your /etc/fstab:

# /windows was on /dev/sda6 during installation
UUID=D1B4-28B3  /windows        vfat    utf8,umask=007,gid=46 0       1

You do not have a /dev/sda6, nor a partition with the UUID D1B4-28B3. I guess you will be getting a "cannot mount" error on bootup.

Wow thanks for the quick reply. I'll go and switch back over to Ubuntu and update Grub. As for the not having a sda6 (which makes sense lol), should I remove that line from fstab? Or is that possible lol. Sorry for sounding like a newb, I just have basic knowledge of Grub. I am still in the learning process.

Thank you very much. I replaced the line and it worked perfectly. As for the cannot mount error on bootup you mentioned I may be getting, I haven't encountered to date. If I do I will see if I can't fix it.

Thanks for that Bootscript btw. it's very useful.
