I have connected my hard drive from my laptop to my PC and now my old Windows 8 is shown on the hard drive even though I have Windows 10 on my actual hard drive when I select the hard drive
"Intel UNDI, PXE-2.1
And the ad This product is conversed by one or more of the following patents
I have an AMD Ryzen 5 and an MSI B450 A Pro Max motherboard
If I understand it correctly, the PC now boots the laptop hard drive.
You would have to change the boot order in the BIOS
Vllt also works, un-wire laptop hard drive. Start Windows 10, as always, then connect the hard drive, copy files that are important to you and then format the laptop hard drive if desired.
I've already done that but it doesn't work
If you have already tried both, unfortunately I have no idea.
You have to set the boot order in the BIOS so that your actual hard disk is in the first place in the boot order. The key combination with which you get into the BIOS when booting is in your manual and is usually also briefly displayed at the bottom of the screen during booting.
Do you have any idea how I can get the Windows boot manager back on my normal SSD?
Unfortunately I can't tell you now from the effeff
That already did that, the problem is that the Windows Boot Manager is apparently on the old hard drive…
Apparently there's no boot entry on the new installation. If you boot your computer with an installation stick and select the "Computer repairs" option, you can select the "Start problems…" option under Troubleshoot. The system will then automatically try to write the boot sector to the start partition.
So do I have to buy Windows again?
