Does this indicate that I can boot straight into Windows and remove linux partition at my leisure, or am I just being paranoid from several recent mishaps, involving several reinstalls on several PCs? Another entry says `[UEFI – TOSHIBA…` blah blah, my HDD. One for Ubunutu, obviously, and the other says Ubuntu, but actually takes me into the dual boot menu that I'm familiar with. This PC's BIOS is a bit different than I'm used to (used to a bit older hardware), and there are two entries for Ubuntu. But won't deleting the linux partition also remove GRUB, locking me out of Windows until I boot into the installer somehow? After I've done this, and used Windows for a few days, how can I remove Ubuntu then? I don't have a large enough USB drive, or anything else to boot Windows from, which is why I've used this method. I don't know if you're still replying to comments, but it's worth a shot. Select “Windows 10” from Grub menu and continue installation. Save this file and restart your computer. You need to set the root and filesystem type according to the location where you’ve extracted the ISO image. Insmod ntfs # This line is not necessary #ĭrivemap -s (hd0) $ # This line is not necessary # Insmod part_msdos # This line is not necessary # 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. Just remember, extract the ISO in just under the Drive root and NOT TO ANY SUB FOLDER. So, you have to extract the ISO to any other partition of your hard disk and then boot from there. But, there is NO way, GRUB can Boot directly from Windows setup ISO file. I tell you how to boot directly from any linux ISO. Install Windows 10 from a linux PC without Burning to DVD or a bootable USB Pen drive.
