10.04 Lost Dual Boot (Windows 7)

**tsaunders** · March 23rd, 2010

I installed 10.04 this morning and now I can't get into Window 7, it just comes up with a flashing cursor when I select Win7 from the Grub menu.

Is there a way to fix this or do I need to run the repair disk for Win7 and start over?

D/l and run bootinfo script and post its complete output.

You'll need to boot from Windows 7 installation DVD into recovery console and use the following commands

Code:

c:
bootrec /fixmbr
bootrec /fixboot

I was afraid of that.

Will I still have Ubuntu and Grub or will I need to reinstall it again?

**prodigy_** · March 23rd, 2010

Hmm. Actually "bootrec /fixmbr" may be not necessary. Try without it first - this way you'll keep Ubunutu and Grub. Your MBR seems to be ok, so it's probably just a broken boot sector (there's currently another copy of Grub2 in the boot sector of your Windows partition).

**andrewthomas** · March 23rd, 2010

You installed grub2 to your windows partitions instead of just to the MBR.

So do I need to run the first part

Code:

sudo fdisk -l

Then run the repair option from the dvd or just the repair option from the dvd?

It's a part of bootinfo, so no need. Your windows bootloader is on /dev/sda1.

Anyway, even if you'll use "bootrec /fixmbr" you won't lose your Ubuntu installation permanently. You can always reinstall Grub from Live CD.

Ok I am going to run this from the repair CD
