BIOS and UEFI issue

alekhka said:

Can you please give a link on how to do it? and should I flash a new UEFI firmware??
Many older laptops i dealt with could install easyUEFI but not mine. Why?

Thanks

Do not go there if pc does not support EUFI. If it does, juts make sure eufi (or csm) option is set, or it can read eufi usbs and decide itself.

You do not need to use tools like Easyeufi.

Simply download iso and use rufus to create a windows 10 eufi install (selecting gpt partition scheme on right).

Then boot from usb, select clean install and delete all existing partitions (back up any valuable data first).

If you only intend to run window 10 on this PC, not really worth changing to eufi anyway.

I am thinking of dual booting with Kali linux and want to have a beautiful bootloader (rEFInd). So all this ruccus. Is eufi=uefi??
Do i need to format all partitions or only C drive?

Sorrry uefi of course!
