I am attempting a rather unusual task, so I am aware there might not be an easy solution for this.
I have a ThinkPad X270 with a NVME ssd with windows 10 installed and a half sized empty 120GB ssd. (Both are M.2). My goal was to boot up to Windows 2000 either from the smaller drive or pendrive. Attempting multiple workarounds all ending in a failure here I come.
Here is the list of what I tried:
-Before all this I configured the bios to work properly (secuteboot off, legacy bios support enabled etc.)
- First I tried to install the windows to USB. I created a WinSetup from USB drive and then a E2B one from it. I ran it in the system, it didn't detect any of my internal drives so the only option was to install to the USB itself, to wich I got an error saying windows install doesn't support removable drives with multiple partitions.
- Next I tried to just make a Winsetup from USB flash drive and tried to run it but that resulted in "Inaccessible_Boot_Device" error. After that I repeated the same thing with a setup CD, my laptop doesn't have a internal disk drive one so I used a USB one. Then the setup freezes on the "Setup is starting windows 2000" screen. I tried to disable the ACPI (pressing F6 and selecting standard PC), wich again resulted in "Inaccessible_Boot_Device" error.
-Next I installed Windows 2000 on a VM, extracted the vdi to a raw iso file. I tried cloning it directly to the SSD, however Rufus doesn't recognize non-removable drives, so I first copied it to the USB with Rufus and then ran a recovery tool to clone it to the ssd...wich refused to boot up. The USB however did boot up , but I got a ACPI incompatibility error. I went back to the VM, disabled the ACPI in the system, cloned the disk again and repeated the process. This time I instead got the "Inaccessible_Boot_Device" error.
At this point I ran out of ideas and didn't know what to do. From my understanding Windows is missing the drivers to read trom the USB ports (wich I think are both 3.0) but I have no idea where would I possibly get them and how would I apply them.
I don't have any other computer that has both a disk drive and a m.2 slot, neither do I have any computer that has a hdd and a m.2 slot at the same time. Is there something I possibly am missing out in one of the attempts or is there another method I could try?
