How to make Windows surface pro 7 and Astra linux friends?

Question

linux

Good afternoon. There is a task by the nature of activity with which it is impossible to cope in any way. There is a Windows surface pro 7 tablet, there are also Astra linux several different versions. So astra absolutely refuses to be put on the tablet.
I tried to install from a disk, from a flash drive, I recorded images in MBR and GPT format. But everything is in vain when starting from a USB flash drive, everything just freezes, the installer does not start. At the same time, Win10 and Ubuntu 20.04 are successfully installed (Now Ubuntu is there). Astra images are working, I recently installed them on full-fledged PCs.
It is not possible to migrate the system from another PC to the hard drive of the tablet, since the SSD is soldered in the motherboard, and disassembling this tablet is a dubious pleasure. Through Ubuntu, I tried to make a second Grub partition, but it does not see the iso image either on a flash drive (you don’t see a flash drive at all), or inside Ubuntu itself (although I may not have enough Linux skills for this).
In general, please help.

Versions Astra smolensk 1.4, Astra smolensk 1.6, Astra orel 2.12

PS Astra orel launches the setup interface, but when any mode is selected, the system hangs. Other versions do not even descend to such luxuries.

PPS Previously, they put on this miracle DELL Venue 11 Pro i5 128Gb and everything worked.

Answer 1

Maybe she just does not support iron?

Answer 2

Since smolensk is a special edition, you can only write to the support, anyway, nothing can be done with such an edition.
