I replaced the motherboard and CPU, but the Windows installation is still not working.
I replaced the motherboard and CPU, but the Windows installation is still not working.
What previous components were used? Which updated parts are now in place? Which Windows release is currently active? Does the latest setup include secure boot enabled automatically? (This might be a concern)
I upgraded my system from an i7 9700 to an i5 12600k using a Gigabyte Z390 U board and ASUS TUF Z790 Plus D4. The operating system is Windows 10 Pro, but I’m not sure what version it was at the time.
consider UEFI or Legacy options and try setting the boot method. Legacy also known as CSM. Ensure your old Windows uses an MBR main boot record instead of GPT. This setup supports drives up to 2TB but won’t work with Windows 11 updates. You can convert MBR-formatted disks to GPT to enable upgrades. However, it’s best to wipe all partitions and install fresh after upgrading the board and CPU. If you need to retain your license, it may be tied to the old mainboard’s SSID or linked to a Microsoft account on Windows 10, which can then be reclaimed for the new PC via www.microsoft.com.
