Router OS 7 on UEFI

I experienced same problem.
It is easy to just instalI RouterOS 7 x86 from iso on uefi capable virtual machine but I wanted to boot use CHR v7 as LXD virtual machine.
It seems that CHR has everything needed to boot via uefi, but its partition table is some kind of Frankenstein between GPT and MBR. Also partition that has efi files on it is formatted as ext2 so it is not in line with UEFI standard which require that EFI files are stored on FAT/16/32 partition. Bellow is a script to correct this issues. I was able to boot it on LXD, qemu/KVM and hyper-v gen2 via uefi. Secure boot is not possible, efi file is not signed by Microsoft.
My script require that you have linux with installed following packages so it can operate and has to be executed with root privileges.

the original solution.
but there are some problems as a result of using it: when you try to boot into hyper-v gen2, it loads, and even there is external access (mac winbox), but the local console keyboard is not available.
it does not respond to clicks.
in case something goes wrong with the network, it will be impossible to restore via the console

@Marciboy, just curious but what’s the reason do you need gen2?

all modern operating systems can be loaded into uefi, consider this one of the stages of standardization: let all virtual operating systems be loaded into uefi, if possible.
there is no reason not to make boot support in uefi.
