For those who couldn't install this OS using rufus or any other tool like ventoy or etcher.
Simply Follow these steps:
First please note that i'm installing it on a x64 physical machine and not a VM or a 32bit machine so installation and environment differs a little. That's why some people didnt complain and others did (like me).
Requirements ONLY FOR 64BIT USERS:
- Another Windows x64 20H2 Build / ISO from this forum
- Pre-installed Windows 10 x64 on a separate machine
- Powershell
- Rufus (recommended)
- 7zip
Steps:
1- copy and mount hydra iso on a separate machine and copy the "
install.esd" file from the sources folder into somewhere like
C:\Users\<user>\Desktop\install.esd
2- open powershell as admin and type in the following command BUT CHANGE <user> into your windows account name!! :
Code:
dism /Export-Image /SourceImageFile:C:\Users\<user>\Desktop\install.esd /SourceIndex:2 /DestinationImageFile:C:\Users\<user>\Desktop\install.wim /Compress:Max /CheckIntegrity
what you need to know about this command:
this will convert the ESD file into WIM file, then select "/SourceIndex:2" which is basically x64bit only because the setup have both 32bit and 64bit and then it will check for the file integrity if it is valid.
just make sure the source and destination paths are set correctly.
3- copy/install and open rufus on the separate machine and select the predownloaded " Windows x64 20H2" iso other than Hydra (other than this build)
4- burn the image into a flash drive / usb stick
5- once done, copy and replace the file located in
<flash drive>:\sources\install.wim with the one we converted and is located at
C:\Users\<user>\Desktop\install.wim - depends on your path
6- on the separate machine goto "
C:\Windows\Boot\EFI\" and copy the file "
bootmgfw.efi" into
<flash_drive>:\boot\efi\ and rename/name it "
bootx64.efi" ----
DO NOT COPY "bootmgr.efi" IT WILL NOT WORK
7- safe remove the usb stick / flash drive and close everything then plug it in the destination machine and enjoy Hydra.
Important Note: Dont mind the Setup UI as it is different from the picture shown in this thread and that is because we're using another build's "boot.wim" in order to boot the image.
I have spent 10 hours non stop working on this to get it to work and i hope it helps anyone else.
