Не работает UEFI (Проблема с разрешением)
Здравствуйте!
Пытаюсь создать диск восстановления из ATI + ADD: После обновления в ATI не получается добавить ADD. Если же я делаю диск в ADD, то все проходит замечательно и диск загружается как в обычном режиме, так и в UEFI с меню выбора, но в маленьком и растянутом разрешении. В справке я вычитал, как добавить свое собственное разрешение: при создании добавить в строку параметров: vga=0x34с - что соответствует 1920x1080 и 16bit. Записываю диск и при загрузке в uefi всплывает меню выбора и тут же пропадает, и загружается Windows. В обычном режиме все работает и разрешение правильное. Подскажите, в чем может быть проблема? И еще, у меня Windows 10 на диске GPT - мне обязательно загружать Акронис через UEFI или можно через старый загрузчик, проблем не будет?

Thank you very much for your help, Steve!
Despite the fact that I wrote in Russian, you understood me correctly. I will follow the instructions you provided and leave a response. One small question: is it safe for me to use ATI bootable disk for in Legacy BIOS mode for now, despite my Windows 10 is installed in the UEFI mode (my motherboard supports both modes)? I searched on the Internet, but I did not understand, does it affect something?

Dmitriy, this question arose yesterday in the 2017 forum with another topic: Slow backup speed where I gave the following answer:
I would recommend caution when advising to use Legacy boot mode for Acronis Rescue Media for computers which boot Windows in UEFI mode. This may work fine for creating backups but may cause problems if you take this same approach when attempting to recover your backup to the same computer if the incorrect boot mode is used.
See KB 60131: Acronis True Image 2018: how to restore your computer with WinPE-based or WinRE-based media and in particular the guidance at step 2. of the procedure outlined.
Finally, see webpage: BIOS Mode - See if Windows Boot in UEFI or Legacy Mode
The key issue, to my knowledge, would mainly impact on recovery, where if a Legacy boot PC is recovered in UEFI mode, it would result in the disk being converted from MBR to GPT. See the ATI 2018 User Guide: About recovery of dynamic/GPT disks and volumes then scroll down to where it shows a table with the heading Partition style after recovery

If your machine boots in UEFI mode DO NOT boot the recovery media in Legacy mode. Any recovery of a backup image if you do so will fail as the recovery will be set as a Legacy boot disk.
On UEFI boot machines display resolution when booted to boot media is controlled by the UEFI itself via GOP (Grphaics Output Protocol). This sets resolution to the native display resolution of the monitor. If the UEFI GOP is unable to do that then the default VGA resolution of 1024 x 768 is used.
If you have Secure Boot enabled in your machine bios you might try disabling it then boot the media again. It might solve your issue.
It sounds like you have created a Linux based recovery media, if you have and turning off Secure Boot doesn't work then I have not idea how to address your issue.
If you are using the default WinPE media then you can get passed this issue by using the Windows 10 WinPE version 1703 or above ADK. OEM's had this same issue so Microsoft built in a fix in these latest versions of the Win 10 WinPE ADK. This will only work when creating WinPE media, WinRE media does not support the fix.
