I haven't been able to get feature updates for a long time. I couldn't work out why. It's an old Win7 desktop, upgraded to Win10, MB/cpu etc have been changed in its lifetime. I don't want to do a clean reinstall. All my bios/drivers/etc all up to date. Deleted my AV. Turned off quick BIOS. Tried media creation tool on USB. I ran SetupDiag Operation failed: Update Boot Code. Error: 0x80004005 I found C:\$WINDOWS.~BT\Sources\Panther\setuperr.log https://pastebin.com/t7BXHRiR Says a lot of BCD stuff at the end. What should I do?
