Can't get back to Windows from Grub.

[Enlightened Shadow]

Hey everyone. I just did a fresh install of Windows XP Home Edition and then a fresh install of Ubuntu 10.10. I can't get Grub2 to find the Windows partition using the prober though.

Here is the output of the Boot_Info_Script005 file.

Any help would be greatly appreciated.

Sadly, windows will not run from a logical parttion (/dev/sd5)


sda1: __________________________________________________ _______________________

File system: Extended Partition
Boot sector type: Unknown
Boot sector info:

sda5: __________________________________________________ _______________________

File system: ntfs
Boot sector type: Windows XP
Boot sector info: According to the info in the boot sector, sda5 starts
at sector 63.
Operating System: Windows XP
Boot files/dirs:

You will need to repeat the installs, and this time take control of them.

Might I suggest the following layout:

/dev/sda1 ntfs XP (12 gigs)
/dev/sda2 ntfs shared data for Windows and Ubuntu (movies, music) - (about 140 gigs, whatever the other partitions don't use)
/dev/sda3 extended partition to the end of the drive
__/dev/eda5 ext4 '/' root partition for Ubuntu (10 gigs)
__/dev/sda6 ext4 '/home' home partition for Ubuntu (10 gigs)
__/dev/sda7 swap (Size of RAM + 10%)

p.s. I have a guide I can post with pictures for the Ubuntu part - would you like that?

[Enlightened Shadow]

Yes please and thank you. I had a feeling that I was going to have to do this.

[Hedgehog1]

NOTE: These screen shots were for a Windows 7 system, and that needs an extra little primary boot partition. So sda5-sda7 are in extended partiton sda4 on the picutres, but yours will be in /sda3 since you are running XP.

In gparted, create 4 partitions:

1) sda3 (extended partition to the end of the disk)
2) ext4 '/' (10-20 gigs)
3) Linux swap (Size of RAM + 10%)
4) ext4 '/home' (the rest of the disk space)

http://img215.imageshack.us/img215/8985/01gparted.png

Once your three partitions are laid out, you will start the install and eventually get to this screen:

http://img829.imageshack.us/img829/4196/02specifypartitons.png

Here is what the allocation screen looks like:

http://img27.imageshack.us/img27/6770/03allocdrivespace1.png

First, make /dev/sda5 your '/' (root) partition:

http://img31.imageshack.us/img31/7520/04allocdrivespace2.png

http://img130.imageshack.us/img130/9673/05allocdrivespace3.png

Next, set up the swap partition. This usually sets itself up just fine, but double check it.

http://img263.imageshack.us/img263/7656/06allocdrivespace4.png

[Hedgehog1]

The last partition to setup is the '/home' one:

http://img202.imageshack.us/img202/6828/07allocdrivespace5.png

This separates your documents and 'stuff' from the system files and 'stuff' in the '/' partition.

This brings you to here:

http://img34.imageshack.us/img34/6017/08allocdrivespace6.png

Please install the Boot Loader on /dev/sda ! (not sda1 or sda5 - just sda)

Press "Install Now" and you are on your way:

Here is a view of the final layout of the partitions:

Great work Hedgehog1 :-)

I am going to follow the steps as it is given by you. Much appreciated your help. :-)
