There will be a key you would have to repeatedly tap to enter the BIOS/UEFI. You need to know which key this is before you start everything. Look up “Key for BIOS in Model PC“. For those with a FrameWork PC, try F2. Other PCs will likely have a different key. This is usually the delete or one of the F keys, so you could always try to be random about it, but it would make more sense to learn the key ahead of time.
