Reinstall, had to disable UEFI. Driver warnings, yet everything works
Hi. Six months ago, I built this PC using a new SSD for the OS and two old HDDs for storage. ASUS mobo and Intel processor. The OS installation didn't cause any problems.
Due to constant BSODs last week, I decided to reinstall the OS. At the 'Where do you want to install Windows' screen I had this message against ALL THREE drives:
'Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.”
I entered BIOS and reset it to Default (assuming that would be its state six months ago). Same story, unfortunately. So I did some googling and managed the install by accessing BIOS/CSM/Boot Device Control and selecting 'Legacy OPROM only' (as opposed to UEFI & Legacy OPROM only).
After the install, I attended to my drivers differently than last time (where I went to the ASUS website). Instead, I installed Intel's 'Driver Update Utility' which only found one driver for me – graphics. Given that I already had sound and internet connection, I was happy – the mobo must have had the proper chipset and LAN drivers.
After all that, here's what I'd like to ask you:
If 'default' BIOS wouldn't let me reinstall, why did I have no problem the very first time?
I presume I'm not benefitting from UEFI? Should I be bothered?
In Device Manager/Other Devices, I have 3 yellow triangles: a) Ethernet Controller, b) PCI Simple Communications Controller and c) SM Bus Controller. Given that I have all the functionality I need I'm inclined to just ignore these warnings, what do you think?
Thanks for taking the time to read this and perhaps offer your thoughts.
