Windows 7 SSD won't boot in machine with Ubuntu HDD. Both have bootable drives. How can I get dual-boot to...












0















My Dad installed Ubuntu (Linux Mint) on the HDD in his gaming computer (go figure) as he didn't like Windows 10. I got him a game for us both to play, which he has been unable to install on Linux (we don't want help with that, thanks).



I've formatted his SSD with Windows 7 using my own computer (call it "Computer M") and it works absolutely fine (Computer M is a windows-only machine). When I mount it in his computer (call it "Computer H"), and set the boot order so the SSD goes first, it won't boot, it crashes after the first few dots of the windows loading screen appear.



On ubuntu i've tried "sudo fdisk -l" and here's what I get:



"Disk /dev/sda: 232.9 GiB, 250059350016 bytes, 488397168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x84b7372f

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes

/dev/sdb2 1050624 1953523711 1952473088 931G Linux filesystem"



If I try "sudo os-prober" nothing appears.



Using "sudo update-grub" I get the following, which has a distinct lack of the word 'windows' anywhere:



"Sourcing file /etc/default/grub'
Sourcing file
/etc/default/grub.d/50_linuxmint.cfg'
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-4.15.0-45-generic

Found linux image: /boot/vmlinuz-4.15.0-20-generic
Found initrd image: /boot/initrd.img-4.15.0-20-generic
Adding boot menu entry for EFI firmware configuration
done"



How can I get this dual-boot to work without re-installing windows or starting from scratch? Is it even possible?



The end goal is to be able to choose which operating system to boot into. If that's not possible, it would be great to just be able to boot into windows; when the ubuntu drive is not mounted, the windows drive still won't boot (again - it works fine in my machine).



I have no idea what I'm doing with ubuntu. I've been trying this for hours. If I can I provide any other info that will help answer my query, please let me know :)



Thanks!
