Grub 2 and Windows 7 recognized on wrong device

akuthia · 07-30-2011, 08:29 AM

Ok. so I Had windows 7 installed on a 30 gig partition. Ya woulda thought that'd be enough, but thanks to that OS' desire to install things to C: even when I tell it NOT TO. it wasnt. So I installed Ubuntu, then ran GPARTED, and copied the entire partition to a new one, and deleted the old one. On restart, there IS a windows 7 boot option:

Code:

menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os {
	insmod part_msdos
	insmod ntfs
	set root='(/dev/sda,msdos1)'
	search --no-floppy --fs-uuid --set=root 2C5C118E5C115444
	chainloader +1
}

According to disk utility though, windows is on dev/sda6. What I can't figure out is where/what to edit to change that. I think that i need to change msdos1 to msdos 6, however when I try to change it through the editor in the bootloader, it doesnt work, and doesnt seem to "stick", i try to boot, it comes back to the bootloader, and I go to edit it again and the value is the same.

Tried reinstalling Grub2 from live mode?

Dicking around with Windoze is usually a mugs game. Easier to just expand its partition by moving everything else around. Linux is much more accommodating that way.
Last I looked the Windoze boot code wouldn't boot from a logical partition, but I haven't tried with Win7.

Simplest would be to run update-grub from a terminal - if it finds the Win7 boot files it should rebuild that entry for you. Whether it will actually work (as in boot Win7) will be an interesting question all of its own.

I had tried expanding the partition, for some reason though, even though there was plenty of unallocated space, and other partitions with space, it wouldnt budge.. the good news, it doesnt look like this is grubs fault: it looks like grub is pointing to the windows bootloader ok, but i confused THAT when i copied the partition. Basically, the windows loader is coming back saying "Windows? what wkindows? I aint got no stinking Windows!"

So now i think i need to see if i can edit the windows boot, without doing a MBR reapir from the windows disk, which will kill grub...

syg00 · 07-30-2011, 09:09 AM

Read this.
Try the update-grub first though ... might save you a lot of angst.

akuthia · 07-30-2011, 09:13 AM

The problem is that windows keeps its bootloader, and thats what grub-update sees. It looks like I need to do the update to the windows loader, then come back and do grub, again

syg00 · 07-30-2011, 09:22 AM

Hmmm - if it keeps finding sda1 that implies you didn't really delete it (sda1).
Go to sf.net and get the bootinfoscript - post the RESULTS.txt.

Past midnight here, so if now-one else helps in the meantime I'll check back in the morning.

akuthia · 07-30-2011, 09:33 AM

was I supposed to delete the windows bootloader too? I prefer keeping lots of partitions so i can keep my files and programs straight, so windows took 100 megs for its bootloader, and I had the actual install on another drive...

Anyways here are the results from the script

unlzma: Decoder error

As i said earlier, sda6 is where windows is actually installed. sda1 is where the windows bootloader started, and where i put grub2 when i installed linux.

I didn't even know you could do that - not that I would ever think of installing any Linux software on NTFS.

Interesting setup.
I don't think your problem is with sda1 (which is where the Win7 boot files are), but the fact that those files don't know where you put the other partition - which is the major part of Win7 itself. Like I said, Linux is much more accommodating, it doesn't keep location dependent data in a registry.
I don't know how to help in this situation - M$oft is so fsck'd up with the way they do things, and they don't document it.

This might be problem. You need put Grub on hard drive itself not partition.
