windows 10 installed via bootcamp does not boot after cloning harddrive

I am not sure I could have used the existing EFI partition for linux - I am using pop_os and aparently it requires a 512mb EFI partition, that's why I made a second one, as suggested there.

I would like to keep linux even if I have to reinstall windows.

So if I can resize the existing linux partition while keeping the system the layout would then become:

• disk1s1 EFI - MBR1
• disk1s2 APFS - MBR2 Mac os
• disk1s3+disk1s4 (resized) - MBR3 Linux pop_os
• disk1s5 - MBR4 (Bootable for legacy BIOS) windows on a 100GB partition at the end

I think I can use linux to delete the current disk1s5 and disk1s6, resize disk1s4, leave 100GB unassigned space and then reboot in mac os to do the windows install with bootcamp.

Would this work?

The other EFI partition was needed for linux I think. I know I have free space left, I'll get to it once the windows problem is fixed.

What should I do now?

Yes disk1s3 is the EFI for disk1s4 Linux installation. Moving linux on another drive is not possible. I do have a secondary drive but I want to keep the 3 systems on the primary ssd. Does this mean there is no way I could keep the extra partition currently on disk1s6 even if I reinstall windows via bootcamp?

So if i combine disk1s5+disk1s6 into a new disk1s5 it will end up extending the windows partition?

Hypothetically could it be possible to delete the windows install, extend the linux partition disk1s4 so that it leaves about 100GB at the end of the disk and then reinstall windows via bootcamp in this 100BG space?

As linux is my daily driver I'd rather have it on the biggest space.

So after trying a clean install of Catalina, Windows 10 (directly from the installer usb, without bootcamp), pop_os and refind in that order, I had Mac OS and windows booting fine at first but the linux and/or refind install screwed things up and windows refused to boot from refind ( BlinitializeLibrary failed 0xc00000bb).

I restored the cloned partition from the old 256GB drive with clonezilla, extended the windows partition from linux gparted, which then apparently let Mac OS detect the whole 500GB and got the 3 systems booting back.

Here is the new layout:

/dev/disk1 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk1
   1:                        EFI EFI                     209.7 MB   disk1s1
   2:                 Apple_APFS Container disk2         127.0 GB   disk1s2
   3:                        EFI NO NAME                 536.9 MB   disk1s3
   4:       Microsoft Basic Data BOOTCAMP                308.9 GB   disk1s4
   5:       Microsoft Basic Data                         63.5 GB    disk1s5

I have too much space on my windows partition but it'll have to do for now. I am clearly out of my depth here, I will have to do some more research on the different types of boot before I make any more potentially breaking changes.

I disabled the hibernation in windows because I read it could prevent it from booting in refind. Is there anything else I need to watch out for that could cause the boots to break again?

Thank you very much for your help!
