I am having real trouble getting my dual boot system set-up. I suspect the answer is probably out there somewhere already, but I am new to this and having trouble sorting through all the information.
The story so far is this:
I have a new desktop with Win 7 64 bit installed on an HDD it.
I put in a separate SSD, and installed Ubuntu 12.04 on that.
When I boot, the GRUB menu comes up with the following options:
Advanced options for Ubuntu
Windows UEFI loader
Windows UEFI memory test
Windows 7 loader (on /dev/sda3)
Ubuntu boots ok
Selecting the Windows UEFI option gives me the error message:
"error: no such device: 9273-9636
error: file '/EFI/Microsoft/Boot/bootmgfw.efi.bkp' not found."
Selecting the Windows 7 loader option gives me:
"error: invalid EFI file path"
Worryingly, I can't boot from my Win 7 recovery or install disc to attempt to fix things from the Windows side. I have tried forcing this from the BIOS (or UEFI or whatever it is now) to no avail...not even setting the CD-ROM drive to the top of the boot list works (and weirdly when I try it that, I find that it has moved itself back down the list when I go back in to try again). I also tried selecting the system recovery option from the UEFI boot menu, but that took me back to the GRUB menu.
I am totally at a loss, and without being able to boot from my Win 7 discs I don't even know where to start fixing it (my first instinct is to attempt start-up repair in Windows but I can't get into it or boot from a CD to do that).
I have tried running boot-repair as well but that doesn't seem to have achieved anything. The URL with the output is here http://paste.ubuntu.com/1287871/ if it is useful to anyone though.
I suspect my problem is either that I have installed GRUB in the Windows MBR, or that there is some UEFI/BIOS incompatibility going on but I don't know how to solve it.
Any help much appreciated...but please, treat me like an imbecile and walk me through every step...don't assume I know anything! The point of installing Ubuntu was to learn about Linux, but I didn't quite expect to end up in the deep end like this!
