How to cleanly remove grub and linux?

Question

linux

I decided to put kali linux on my laptop, but a lot of errors surfaced and decided to remove and leave the bootable USB flash drive.
linux installed on ssd, and grub installed on the hard disk with Windows.
can you tell me step by step how to remove it correctly and in what order. there is no disk for restoring Windows, it costs 7.

Answer 1

If you have efi, then you have 2 options: change the boot entry in uefi or copy the window loader from the /EFI/Microsoft/ folder to the /EFI/Boot/ folder. Then, in the BIOS, specify this disk as a boot device. After that, try to reboot, if the windows load, then delete the folder with the Linux bootloader on the same partition (you can not delete it, it will not hurt) / EFI / Distribution_name /, and simply format the Linux partition. And you can do it even easier. Check in uefi whether there is a boot entry for windows, if there is, then set it as a priority, forget about the Linux bootloader (it does not take up space), and format the partition with it.

Answer 2

It is necessary not to delete grub, but to restore the Windows bootloader.
ISO can be downloaded from the Microsoft website, the utility from them is to create a bootable USB flash drive.
