[SOLVED] Will the new Windows 8 PCs work with only Ubuntu installed?

[oldfred]

I know one user posted that his standard procedure (not sure he did it with UEFI yet) is to buy a better laptop, but with only a hard drive. Then he buys a SSD, puts hard drive on shelf in case he later wants to sell system with Windows and installs Linux on SSD.

Ubuntu is now successfully installed on my new HP laptop
with help from Ubuntu, Community, Boot-Repair.
Funny thing - now my grub has over 10 entries.
Ubuntu is at the top, Windoz near the bottom, and a lot of EFI items in the middle.

Some new PCs may work with Windoz removed and some won't IMHO.
I get the bad feeling that more PCs will not work as time goes by.
So I'm not going to try to remove Windoz.
I don't need it, but my laptop may.

I'm writing this message from my new HP using Ubuntu.
Thanks to all.

You can backup & remove entries in grub's menu. All the entries in 25_custom were created by Boot-Repair and it saw a lot of HP .efi files. So it created an entry for all of them. Not sure if needed, but you may want a backup.
You can also turn off os-prober until it gets updated to create correct entries.

# I add this line to grub configuration or turn off the execute bit on 30_os-prober
gksudo gedit /etc/default/grub
GRUB_DISABLE_OS_PROBER=true
or turn off executable bit
sudo chmod a-x /etc/grub.d/30_os-prober
# Then do:
sudo update-grub
Or one liner
sudo echo GRUB_DISABLE_OS_PROBER=true >> /etc/default/grub
sudo update-grub


sudo cp -a /etc/grub.d/25_custom /etc/grub.d/bkup25_custom
gksudo gedit /etc/grub.d/25_custom
Then do:
sudo update-grub

Update
Added Sabayon, but didn't care for it.
I also added Lubuntu, but it didn't work fully.
Then I've added LinuxMint 15, both Cinnamon and xfce.
Xfce is my preferred choice currently.
Still have Ubuntu 12.10 which I use only for boot repair.
And Win8 is still on-board so I can do my genealogy.
Thanks for replys.
