My older Win7 laptop died (power issues). My new Kubuntu computer has an extra drive bay, so I'm trying to get dual boot to make them play nice together in the same machine. Both drives boot fine if they are /sda, and both OS show up on GRUB2.
The Kubuntu is expendable, the win7 is not (school stuff, solidworks and all that jazz). I am on a HP Pavillion dv7 from 3 years ago.
When Ubuntu is /sda, the computer boots to GRUB. I can boot Kubuntu fine, but if win7 is selected (/sdb), it prints the "A disk read error occurred" error.
When win7 is /sda, it boots win7 fine, but with no option for Kubuntu.
Not sure what happens if boot order is switched, as my BIOS only has an option for Internal Notebook Drive. It does know that there are two drives that can be memchecked though.
I think part of the problem may come from this (full log here):
File system: ntfs Boot sector type: Windows 7/2008: NTFS Boot sector info: According to the info in the boot sector, sdb1 starts at sector 2048. But according to the info from fdisk, sdb1 starts at sector 63. The info in boot sector on the starting sector of the MFT is wrong. According to the info in the boot sector, sdb1 has 407551 sectors, but according to the info from fdisk, it has 1984 sectors. Operating System: Boot files: /bootmgr /Boot/BCD
But I don't know enough about Ubuntu to fix it, and I'm certain I'd break my Windows forever. Should I reinstall Kubuntu when both drives are present? What other info would be helpful? Any help would be very appreciated.
