ok so for WFH i got a dell e5470 with 256 GB M.2 . now the purpose is over and i want to format that laptop for personal use. Deleted partition but from format/delete drivers, after that it gives a Disc Controller not found error . i have factory reset the Bios, turned off safe/secure boot, toggled UEFI/Legacy ? any solutions ?? if i remove m.2 and install os from different system will it work ?
