Glad you got Mint working again. Copy/replace and Backup are almost the same thing.
It seems to be a problem with GRUB that it won't show Windows 8. Try updating GRUB, or look at this page: http://askubuntu.com/a/211070
Thanks for your help and sorry to be so dumb BUT the saga continues
Tried updating GRUB but could not do any good. Then fiddled with my BIOS and lost Mint
Managed to "Repair computer - Auto Repair" from the Win8 DVD and that is now 100% OK but I now can't access Mint. The "usual" message on booting up "Drive 1 not found: Serial ATA, SATA2 - Strike the F1 key......"
Booted to the Mint 12 DVD and
(a) Can examine Drive 1 (the LINUX drive) in Disk Utility and note that "Partition Flags: Bootable" so it should be bootable I reckon.
(b) Can access all documents/folders on Drive 1 as Administrator.
(c) Can open GRUB folder in the BOOT folder on Drive 1 as Administrator.
Any suggestions please to try and get Disk 1 back before I repeat the reinstallation of Mint 12.
Here is a screen shot of my setup from the Win8 side of things:
Thanks for your patience......Mike
