Windows 7 doesn't appear in grub list, but still exists
Hello together!
I'm new to linux and wanted to try it out a couple of weeks ago. So far I'm quiet happy with it, but I still need to use Windows for professional reasons. After a Linux reinstallation, I can not choose between Linux and Windows in the grub list. The remaining options there are: Ununtu, Advanced Ubuntu Options, and the two memory tests.
I tried so far:
$ sudo update-grub
$ grub-install /dev/sda
but it didn't help. I also ran fdisk -lu and here is what I got:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors

Partition table entries are not in disk order
I also ran the bootinfoscript and will post the result file below. Unfortunately I cannot really conclude anything from this file. Further more I DON'T HAVE A WINDOWS CD here.
Here the bootinfoscript file:

I really need to get my Windows back to work and would like to keep Linux for personal use
I appreciate any help and please let me know if you need more information.
Thank you so much!!

Re: Windows 7 doesn't appear in grub list, but still exists
Welcome to the forums!
Try update-grub2
Also, can you post the output of update-grub please?
Re: Windows 7 doesn't appear in grub list, but still exists
When grub runs the update-grub, it also runs os-prober to find other operating systems. But if it cannot find any, it does not add them to the menu.
Boot script was not able to open sda1 which probably is your Windows install as partition table says it is NTFS and has boot flag.
If Linux cannot mount it, it may need chkdsk or you left it hibernated. Both chkdsk & hibernation set flags that Linux sees to not mount a NTFS partition and cause more issues.
From your Windows repairCD or Flash drive, try running chkdsk.
Vista or 7 repair
Comments by others:
Repair often does not work, some say run 3 times others recommend the command line bootrec.exe
Always run chkdsk and run again until there are no errors, that may be all that is required
chkdsk c: /b
/b includes /r

Re: Windows 7 doesn't appear in grub list, but still exists
+1 to oldfred's suggestion. Get your win7 dvd or rescue cd (or make one rescue cd on any win7 computer at a friend) and run chkdsk from the repair command prompt. That should be the first step.
When the chkdsk is done you can try booting ubuntu and running update-grub to see if it will detect it.
I also don't like that the boot info says grub2 on /dev/sda is looking for partition 72 which is not true. But I think it can work as it is, your ubuntu seems to be booting fine.
Re: Windows 7 doesn't appear in grub list, but still exists
Hi and thanks for the fast replys!
@ Virtuality314: I tried update-grub2 and that's what it sais:
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.5.0-26-generic
Found initrd image: /boot/initrd.img-3.5.0-26-generic

Found memtest86+ image: /boot/memtest86+.bin
done
To get a Win rescue DVD I might have to wait until monday to ask work colleagues.
Once I have it, I boot with the DVD inserted and will run the chkdsk command in the repair command prompt. Then I should try to reboot Ubuntu and update grub again. This might help me. Is this correct so far?
Would the exact commands be?:
chkdsk c: /b
/b includes /r
Thanks a lot! Once its solved I'll definitely mark it that way!

Re: Windows 7 doesn't appear in grub list, but still exists
I actually get this screen just after the moment where grub is supposed to appear:
Attachment 240458
Maybe this is related to the Windows partition...

Re: Windows 7 doesn't appear in grub list, but still exists
Re: Windows 7 doesn't appear in grub list, but still exists
I have no idea what that error means. But since the boot info script can't open the ntfs partitions sda1 and sda2 to look inside, there is definitely something wrong with them. For that reason, the win7 boot files are not even detected and no entry is made in the grub boot menu.
Yes, run the chkdsk and see how it goes with sudo update-grub after that. On occasions you might need to run chkdsk few times, but run it once for a start.
Re: Windows 7 doesn't appear in grub list, but still exists
Hi again,
so I created a Win7 32-bit recovery CD today at work and just tried to boot from it but it doesn't work. The CD definitely starts turning and I get a message at the very beginning of the boot process saying: "Press any key to boot from CD/DVD..." and so I do but the CD stops spinning and the screen stays just black. Furthermore I can't see the disk on Linux (at least it doesn't show up in Dolphin and there's no device notification). When I then started to boot Linux, I also got an unusual screen, saying something like: (appr. 20 lines like that)
end_request: I/O error, dev sr0, sector *some number*
Buffer I/O error on device sr0, logical block *some number*
After having burned the CD today, I checked the content and I could clearly see a file called "bootmgr" and two folders: "sources" and "boot". I actually downloaded the iso file because everybody at work runs 64-bit Win7 OS.
Can anybody help? Thanks so much!
Re: Windows 7 doesn't appear in grub list, but still exists
Sounds like it is not a bootable CD, or not correctly burned. Often best to write at slowest speed your CD/DVD allows.
I now prefer flash drives, but the Windows repair install is tiny or 256 to 300MB. I ended up repartitioning it, installing grub2 over the top of Windows and chain loading back to Windows and adding a bunch of Linux repair ISO to boot directly from grub, to have an all in one repair flash drive.
Make your own Windows repairCD (not vendor recovery):
