Hi, I'm a novice to EasyUEFI, but used multiboot before with older BIOS systems.

I have an ASUS laptop with an updated UEFI BIOS and Windows 11 installed. The OS drive is large enough, so I want to copy to it another Windows 11 install from a different PC that has a different set of apps installed, and plan to add its boot entry to EasyUEFI.

Before doing that I wanted to clarify the following:

- if the 2nd Windows install currently runs from another UEFI PC, what partitions should I clone to the ASUS laptop drive in addition to the 2nd Windows System partition? Should I also copy UEFI and Recovery partitions from the 2nd PC? Will the 2nd UEFI partition be used at 2nd Windows startup on ASUS laptop, and will the 2nd OS Recovery work as expected if needed?

- if the 2nd Windows install is MBR disk based from a non-UEFI older BIOS PC, what partitions should I copy to the ASUS laptop drive in addition to the 2nd Windows partition? Should I also copy the MBR sector and Windows Recovery partition, and will it work if needed or be used at all?

Thanks a lot guys

My recommendation is to simply clone the C: drive from the 2nd Windows installation to the ASUS laptop. Then you can use EasyUEFI to add the new Windows boot entry to the Windows boot menu (BCD).

If you only clone the C: drive, you don't need to consider the MBR vs. GPT issue.
