I have Acer Aspire XC600, originally with Windows 8.1 and now with Windows 10 HOME. I want to install Windows 10 Pro. I have the DVD and licence key but I CANNOT get it to boot from DVD.
I want to wipe the whole disk using Partition Magic and start again.
I know about Shift restart which gets you into various obscure startup options such as safe mode, but UEFI/Legacy is not in the list of options shown, and anyway the screen freezes and does not allow any of the options to be selected.
When booting I see the UEFI startup screen for an instant and (I think) it says press delete for UEFI or F12 for startup options but I can't press delete/F12 fast enough to get in.
Ideas please?
