Need some advice!
Yesterday I performed NVRAM reset on my VivoBook S510UNR.
This VivoBook has dual boot - Windows 10 and Big Sur.
After reset only Windows 10 is loaded. All UEFI configurations have disappeared from the list of downloadable configurations in the BIOS. There are only two Windows bootloader configurations left (I have SSD and HDD, while both Windows 10 and Big Sur are installed on SSD, and the UEFI partition with SSD is simply copied to HDD). OpenCore does not start, even when I manually create the configuration using the BIOS (BOOTx64.efi and OpenCore.efi).
The long way I propose to solve this problem without reinstalling Windows and macOS is to defragment the HDD, allocate a 50 GB area on it and install the "new" BigSur there.
I think that after that both Windows and the "old" Big Sur will become available.
Dear colleagues, can you suggest an easier way? For example, it may be possible to somehow enter the appropriate boot configurations into NVRAM?
