I am using Ubuntu 18 on my machine and the world is beautiful. Unfortunately I need to run Windows 7 as well. So I got myself an additional SSD and installed it there just to find out that my machine will continue booting straight into Ubuntu like Windows ain't a thing. Holding F12 to select boot option manually would let me boot into windows but I'd like to have grub ask me which one I'd like to boot into. After I did some reading I realized Windows was installed in BIOS (Legacy) mode. So I looked up how to install Windows 7 in UEFI mode and the instructions were pretty straightforward:
- format flash drive as Fat32
- flag as bootable
- extract 100% legally obtained windows ISO on the drive
Sadly at this point I can see my flash drive appear in the connected USB devices list in my BIOS but it does not recognize it as a bootable device. I'm stuck at this point as I don't know what more to look for..
