Can win 10 installed in traditional startup mode be changed to UEFI startup?

1. Use DiskGenius to convert partition table into GPT format (toolbar hard disk → convert partition table type into GUID format). 2. Compress a partition with the size of 100MB from the existing partition, and format it into FAT32 format as EFI boot partition. 3. Put the required EFI boot file into the partition and set the boot.

4. Restart, enter the BIOS, change the startup mode to UEFI, and load the shell file in the EFI partition.

Then it can be started through UEFI. Note: Before step 4, you must confirm that the first three steps have been completed correctly, otherwise it cannot be started.
