Install Windows 10 from a linux PC without Burning to DVD or a bootable USB Pen drive.

In my previous video,

I tell you how to boot directly from any linux ISO. But, there is NO way, GRUB can Boot directly from Windows setup ISO file. So, you have to extract the ISO to any other partition of your hard disk and then boot from there. Just remember, extract the ISO in just under the Drive root and NOT TO ANY SUB FOLDER.

Now add a new menuentry in Grub. open /boot/grub/grub.cfg ( or /etc/grub.d/40_custom after editing this file run sudo update-grub ) file in a text editor with root access and add these lines preferably at the end of the file.
_____________________________

menuentry 'Windows 10' {
set root=(hd0,5)
insmod part_msdos ### This line is not necessary ###
insmod ntfs ### This line is not necessary ###
insmod ntldr
drivemap -s (hd0) ${root} ### This line is not necessary ###
ntldr /bootmgr
}
_____________________________

You need to set the root and filesystem type according to the location where you've extracted the ISO image.

Save this file and restart your computer. Select "Windows 10" from Grub menu and continue installation.
