Install Windows 10 alongside Ubuntu 18.04

  • 772

I'm trying to install Windows 10 alongside Ubuntu 18.04 because I want to try some games on my laptop, and then go back to Ubuntu.

I have two USB Flash Drives, one with Windows 10 and the other with Ubuntu 18.04.

These are the steps I've done after following some answers here on Ask Ubuntu:

  1. Booted on Live Ubuntu, and shrank my 1TB HDD into a 500 GB NTFS partition with GParted;

  2. Booted on my Windows 10 USB Flash (on UEFI) and installing Windows without deleting the partition or formatting it, just by pressing next ( I also tried deleting it and make a new one with Windows, but I encounter the same issue);

  3. After install, it was directly booting into windows, probably installing other stuff, and this is the annoying part, Windows froze at

    Getting devices ready

    or something like this. I forced it to shut down and then .. continuing to step 4;

  4. I booted again on my Live Ubuntu USB, and I have installed boot-repair, doing the recommended installation.

  5. After installing boot-repair, I restarted my laptop, booted on Ubuntu OS redirecting me to GRUB Boot Loader, I selected Windows everything loaded then I got this error that Windows isn't installed properly and I have to restart and reinstall it.

I really don't know what to do any more, I deleted the NTFS partition and extended my ext4 partition, everything is normal now, but I really need Windows 10, I also need an answer on how to uninstall it and go back to normal.

This is one of the questions I was following, but it doesn't work for me: Install Windows 10 alongside Ubuntu 14.04

And this is the second question, and I was following the first and the second answer, except doing the mount /boot thing because I didn't know what to do exactly: How can I install Windows after I've installed Ubuntu?

EDIT : Here's the summary of boot-repair

windows dual-boot uefi

  1. Remember the step you skipped While installing, it explicitly said don't turn off the system. If you want a clean slate you can boot from Hirens Boot, backup your data and unallocated every partition then merge them. Then start from step 1 again. If you want Windows, Then make sure your CPU architect is compatible with the one you choose in the start up. Second, it takes time so grab a coffee, And Then install Ubuntu on top of it. One more thing try to give windows an unallocated partition instead of a hand made NTFS one. If you all fails, get your HDD checked or get it wiped out clean. And if that failed..... you're in deep s**t.

  2. I believe it's not booting from the usb drive first. You need to check which one you have priority first when restarting. It checks if you're starting with windows or from the usb you have written the iso file on. check this site out(it's the one i used to see how to prioritize booting from my usb) https://www.laptopmag.com/articles/access-bios-windows-10.

    I also used this guys tutorial which really really helped me. https://www.youtube.com/watch?v=MSVV_EoApdo&list=FL6PkExoBTT-JKR6oakVQC8Q&index=2&t=0s.

    Good luck!
