I just installed Windows 7 on an MBR disk (SSD). I tried GPT, but there were a lot of issues. Now, I am unable to boot from Ubuntu USB in Legacy BIOS so I booted in UEFI mode.
When I am trying to install Ubuntu and select manual partition, should I install it in /dev/sda or /dev/sda1 (which is a small ext4 partition I had reserved for boot.)
I cannot designate the partition as boot, only efi boot option is available.
If I install Ubuntu to the efi boot partition , will windows keep working ?
