Installing Catalina without USB

Is it possible to install hackintosh Catalina without an USB flash drive??

I tried doing that by downloading olarila catalina .raw file, then mounting the .raw file in Ubuntu using:

sudo kpartx -v -a ./Catalina.raw

The HFS+ 8.1GB volume was mounted on /dev/mapper/looper10p2, Then i formatted a partition on my internal hdd to HFS+ and issued the following command:

sudo dd if=/dev/mapper/loop10p2 of=/dev/sdb6 status=progress

After that was done , i mounted loop10p1 (EFI) System partition, copied the EFI files to another FAT32 partition, and then rebooted and went to boot menu. Then i selected my FAT32 partition having Clover EFI Files, it worked perfectly and booted into clover, The /dev/sda6 partition was detected as Catalina installer, i clicked on that, then, after displaying some texts, it froze.

Can someone help me?

Gigabyte H310M
