I am facing the following problem: I used a dual-boot of Manjaro and Windows on my laptop. Due to some license problems with Windows, I wanted to reinstall Windows. I thought it would be a good idea to delete the windows partition in GParted in Manjaro and install Windows on the freshly cleaned space. Unfortunately Windows now tells me it can't install on a GPT formated hard drive. Additionaly, I can't boot Grub and Manjaro anymore. As soon as I turn on the PC I start in the Grub rescue mode with the " no such partition"-error. Searching for the partitions with the ls-command I find a few partitions like (hd0,gpt2), which is ext4 formated, so I guess this is my Manjaro partition. Unfortunately, I couldn't make it boot in grub rescue mode. I tried to boot my Manjaro Live USB and repair grub. After inserting the command "sudo mhwd-chroot" it told me it can't find a linux system. On the grafical interface of GParted and the command "lsblk -f" I can see my ext4- Manjaro Partition. Can somebody help me to repair grub and install Windows on the free partition?
So far as I understand it, I had a MBR-partition table (I need it for a windows boot, dont I?) and it seems like I killed it by deleting the windows partition. That's why it tells me I have a GPT partition table and Manjaro and Grub are broken because they were linked to the MBR-partition table. Is my guess right? How can I solve this problem?
Thanks a lot in advance!
Edit: It is an EFI-System.
