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

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:
/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 initrd image: /boot/initrd.img-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 🙂
