- - Win7 wont boot (https://www.linuxquestions.org/questions/linux-newbie-8/win7-wont-boot-859336/)

Hey. I have dual boot my computer with win7 and ubuntu. Ubuntu works fine, however I can not boot into win7. It starts with the windows logo and than it stops and reboots itself. Can anyone help me how to fix this? I have no real experience with linux, so please be gentle.

this is not a linux issue

if windows 7 starts until the part with the windows logo there's nothing about linux anymore as far as windows is concerned

Do I understand correctly that since the win logo is shown, the fact that it doesnt boot does not come from a fault in grub?

That would be correct however you can fix this with a windoze installation disk. What you need is to repair the MBR.But you may have to reinstall Ubuntu as well afterward.

I tried the windows recovery disk. However that didn't work, it only made the computer skip the grub and than try to directly boot the not working win7.

Your grub needs a little help finding the right partition. Use your ubuntu and find terminal.
From terminal

sudo fdisk -l (small L) enter

Copy and paste the results here.

this is my result from fdisk:

Code:

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

255 heads, 63 sectors/track, 121601 cylinders

Again from terminal

sudo cat /boot/grub/grub.cfg (enter)
and paste the results

The grub.cfg file was on another place, I pasted it here:

If you were looking for something else let me know

You will have to give me some time to catch up on the SFS file system.

Why do you have the SFS file system? You are using a file system type that nobody else uses. That doesn't make any sense. Of course it is possible that your disk label doesn't accurately reflect the contents of the partitions. Nevertheless the disk label should say what type of file system is contained in each partition.

Since /dev/sda2 is bootable I would guess that this is where Windows is installed. I doubt that Windows will work on this SFS file system, if that partition contains an SFS file system.

I think you should use your recovery disk to wipe out the entire disk and reinstall Windows. That will put you at a normal starting point. Then if you want Linux you should choose a normal installation with typical file system types such as ext4, ext3. Also your listing from fdisk doesn't show any swap partition. You should have a swap partition until you know more about Linux.

My bad, I missed the spacebar between cat and /boot/..

I think this is where things go wrong (SFS showing up in fdisk), I'm 100 percent sure it used to be NTFS and ext4, when I installed. I dont see how this could ever change in during an ubuntu installation.
About the swap space, you're correct. However that should not be the source of the problems I'm encountering now, or would it?

The reason it is looking like SFS may be this, I have not had time to read, have another project requiring my time now. Read the second tutorial

Note for NTFS users

It appears to be caused by a software that you installed from Runtime. This is the only repair I could find on the subject.

System Info

I believe once that is repaired your boot problem will be fixed.
