Set up Ubuntu alongside Windows 10 on a system that doesn’t use EFI.
Set up Ubuntu alongside Windows 10 on a system that doesn’t use EFI.
The unallocated space was Kubuntu, but I deleted it in the hope it would resolve the problem. sda1 is the main partition. sda2 and sda3 are Windows recovery partitions I never modified. Running fdisk -l shows the disks: sda1 holds 401,882,039 sectors, sda2 has 475,105,279, sda3 contains 132,857,555 with a size of 6.3G. The system labels them as NTFS, WinRE, and XENIX respectively.
This old laptop originally came with Vista Professional. Since I didn’t install Windows, I’m not sure what the SDA3 is—probably a recovery disk. All partitions stayed in place. I ended up copying everything I needed and reformatted the entire drive. Now Windows 10 Pro is installed and functioning properly.
