Of course it's removed. I think changing the bootloader is my last option because I also tried: 1. Connecting the OTG cable to the USB DOM connector directly and use the same USB stick - does not boot. 2. The original USB DOM in Windows is detected as USB 2.0, but in Synology - it does not boot. It seems to me that my USB DOM connector on the motherboard is faulty. I will still try to connect to the terminal and check the booting.

I have the same config in SynoBootLoader.conf: ...root (hd0,0)... Everything loads from the flash drive with VIP/PID F400/F400 and works correctly. But during a soft reboot, the NAS does not want to boot again (it blinks blue again). But if i turn it off physically and boot up again, everything loads correctly. I assume that i need to change the configuration of the GRUB loader (SynoBootLoader.conf) to reboot correctly. Can anyone tell me what to change? Thanks in advance.
