One common cause is that in Windows settings, you need to disable “Fast Startup”. Otherwise, Windows will leave the partitions marked as dirty and they will be marked Read Only.

I previously installed grub2win for an android os
But now i deleted it for this issue but even after deleting it this is not working

Did you go into Windows and disable “Fast Startup”?

[Dusi]

It was already disabled

[dalto]

Is your system legacy booting or UEFI?

[Dusi]

Uefi

Boot off the ISO and try to mount your EFI partition.

Check and see if it mounts read-only. If it does, repair it.

“We” don’t know how are the “settings” from your root + efi partitions.

• Think on it, the efi partition must have flag “boot.” (handmade)
• default is the size from the efi partition 300 mb + fat32
  and 40gb for the system is ok but not much, think on it, you stay default on btrfs file system with snapshot function + “home/user” stuff.
  If you need handmade partitions, the first partition on the hdd must be the efi (flag as boot), then the root partition (flag as root) + linux swap partition (if needed)
• that’s all “gpt” not mbr modus
• to install the iso (downloaded from the homepage)
  to read:
  Garuda Linux
  my mind for your install:
  disconnect the sdd → start live iso over grub2 option use then the option boot with open source driver → start the partitionmanager → delete complete the hdd → use gpt modus → make the right settings for the efi partition (fat32 flag boot) → make the root partition with your preferred size as btrfs (flag root) + swap partition (if) → ok then reboot → once again the live iso start → open calamares and use by settings for the partitions “handmade” → if you have before the right settings done → you read no info from calameres about problems → rdy → install the os → done. Start garuda (disconnect pls the usb/dvd) and ? If you stay on your installed system pls post your garuda-inxi then.
