I tried the ISO linked in your thread with UEFI7 and UEFI mode on the Acer Aspire A315-21 with AMD Radeon R4, but it still froze. Not sure what else to do other than Legacy mode, which does not allow more than 4 partitions.
Only in the early UEFI-laptops (such as Sandy Bridge and Ivy Bridge) and even then it depends on the manufacturer. For instance, my Dell Latitude E6530 with Ivy Bridge has this feature and is what I needed to make it work, but my Acer Aspire E1-531 with Sandy Bridge did not.ruslanshchur wrote: ↑15 Jan 2022, 08:41 Isn't it possible to enable CSM but boot in UEFI? (unless UEFI-only)

Also, Windows Vista will not install on Intel 11th Generation Tiger Lake/Intel Core i5/Intel Iris Xe graphics. While I didn't even try to install it, given the fact 11th Gen has no USB2 ports will make it not work. Even with putting the drive in another laptop, installing, and then moving it back will likely not work due to a likely non-ACPI compliant BIOS 0x0A5 BSOD. You might be able to get it to work if you patch acpi.sys and setup an unattended setup (if Vista supports that feature still), but it's iffy (and unattended setup is necessary as your USB ports would not work and you will most likely not have PS/2 ports unless you can find a PS/2 adapter that works with a port that does not need drivers (which is unlikely).
USB 3.0 drivers (you need to install KB2864202 before installing USB 3.0 driver, otherwise, it will not work):George King wrote: ACPI A5 Patch same as we have for Windows 7
