Hi,
Thank you for posting your query in Microsoft forums.
What is the make and model of the computer?
I would like to tell you that The BIOS is completely independent of any operating system you might install. This is because the boot up process starts with the BIOS, then passes control to whatever boot programs are stored on the hard
disk.
I would recommend you to post this query in Toshiba support forum:
