At least, I think that's what I've done. Certainly it doesn't boot and I get a grub recovery prompt.
I'm trying to install ubuntu 10.04 to a usb key, and the install completes normally, but I think the default option must be to edit the local hard drive's boot system to boot from the usb key - a spectacularly stupid thing to do, given that the whole point of installing an OS to a usb key is that you'll be using it on other PCs. Perhaps this isn't what happened, but I'm now on the same laptop (dell lattitude e6400) using a live ubuntu 10.04 so the laptop is working fine; I can see files on the hard drive.
I've done fdisk -l and I get:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x117d3f32
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 102400 7 HPFS/NTFS
Partition 1 does not end on cylinder boundary.
/dev/sda2 13 9730 78046208 7 HPFS/NTFS
I don't seem to be able to boot from my windows 7 disk.
A lot of the help on the net seems to refer to earlier versions of grub than is supplied with ubuntu 10.04, so the help doesn't work.
Is there anything I can do to get windows 7 to boot? I don't mind using grub to boot windows.
