Corrupted Windows boot and BIOS while dual booting?
in flag

So I was/am trying to install Ubuntu to dual boot Windows and Ubuntu together, but while trying to do so, I went into the BIOS and I believe I changed the boot menu to Legacy - I think it was a drop down from UEFI to Legacy. Anyways, when I restarted it, I now get the Client Mac Addr (no post screen). Thankfully, I had Ubuntu on the flash drive and it went into installing that. After this was installed, ...
