I reinstalled my windows and probably removed clover (no access to macOS)

[Barley194]

Hi, I formatted my windows partitions (all, efi, recovery etc). But I did not touch my macOS partition. (it's on the same disk). Now, after installing fresh windows 10, when I start my PC, it instantly goes to windows. Tried all available boot devices and no one booting into clover. I can't even boot into macos to use the tool to install clover. So I think, I need to do it from windows somehow.
Also tried installing clover into usb flash drive, (don't know if I did it right). Then selected in BIOS this flash drive, and clover loaded. There was even option to boot macOS from the drive it's installed on. But when I clicked on it, it showed me apple logo and after this, it restarting whole PC. (tried multiple times)

Please help me, I really don't want to reinstall whole macOS..

Please update your motherboard, CPU and graphics card information in your Personal Details as stipulated by the forum rules.

Most likely the Windows 10 installation has wiped out the Clover bootloader installed on your disk.

Did you make a backup copy of the EFI folder located in the EFI partition of the disk before you erased everything and reinstalled Windows?

The default installation of Clover most likely created a default configuration which did not work with your system.

We generally recommend installing Windows and MacOS on separate drives in order to avoid the scenario you have encountered. Using separate drives you can disconnect the other drive before you attempt to reinstall Windows or MacOS.

I updated my specs. (both macOS and windows are on SSD if it matter)

I didn't make any backup, completely forgot about it (I did this hackintosh a long time ago).

Is there any way to install new clover? Or what can I do? I don't want to do fresh install, it took me so much time and there was a lot of problems ;/

Back then, I though that the best way is to install both os on the same drive. As I can see now, that's not true.

The problem is, since you did not backup your EFI folder, you have lost your working configuration.

What is the version of MacOS you were running on your system?

My suggestion is, recreate a Unibeast USB stick using the same version of MacOS you have on your system (need a Mac or working hackintosh for that), and then try to ask around if anybody has a similar configuration as your system and ask them for their EFI folder.

After you get that EFI folder onto your USB stick, you may try to use that stick to boot the MacOS system on your disk to see if it works.
