Hm, if we talk about EEE (Embrace, extend, and extinguish) Micro$oft "DOS", using word grub4dos in a Linux topic, then let me inform you that a new-recent Grub4DOS can now boot from UEFI firmware, not only from BIOS. Even a grub1 (special edition from Fedora) could boot from UEFI.
It is useless for Linux (which already boots in tmpfs RAM), but extremely useful for Win11
Because the new UEFI Grub4DOS allows you to boot a WIM image fully in RAM. I mean you can build a full or "reduced" size image like winPE (yes 500 MB win11), compress it with LZ4 and Grub4DOS will load it in RAM. Of course then you need extra RAM for win10 / win11 to run its programs, and applications can be 7z loaded in RAM on-demand from USB etc. The point is that it is NTFS native in memory, but will not premature destroy your NAND flash with its NTFS cache / flush /log writes.
And of course, icing on the cake, no Win7/10/11 registration (aka IP breaking US law) for adventurist.
Adventure is because using a Chinese Boot-loader with a closed source Win11 software. But hey, do not bother yourself too much, you do not audit TC either, you just use it as it is, don“t you? It is all about trust in mankind.
