Grub rescue question, how to remove?

Question

linux

I decided to format the partition on the hard disk where linux was, booted to windows 7, demolished the partition through Disk Management, then created a bootable USB flash drive to install clean Windows, but that's bad luck!
After rebooting, hoping for installation, the command line came up with
error: unknown filesystem
grub rescue>
found a solution on the Internet .. but it didn’t help ..
after the ls command
, I have partitions
hd0, msdos5, msdos1, hd1
and if I work with them, i.e. to load the
insmod normal
mod, then nothing comes out, because an error pops up, they say unknow filesystem.
Okay, God bless him, with recovery, I tried to install Windows through the disk, set the parameters in the BIOS, but as soon as the installation disk is loaded, the command line pops up again with a message.
Boot failure
Press any key to continue

Well, of course, if you press any key, the message pops up again.
And so, is there a way to completely format a hard disk in some other way than bootable flash drives, disks?
Or is there an alternative way?
Help the teapot please!!

Answer 1

it’s not very clear why you need it,
just boot from the installation flash drive and install Windows and format the disks when installing.
