Dual boot windows 10 ,lubuntu 18.04 working but a hassle ( need to press Esc to go to GRUB)
Hello guys,
It's been a while I didn't tinkering with dual boot. Windows 7 and opensuse just work for all these years with BIOS/MBR configuration.
With new laptop,UEFI GPT thing, windows 10 ,I have to deal with dual boot issue again.
And because I use laptop, I decide to post in this section. Hope I'm not wrong.
Quick background:
I use Lenovo Thinkpad E480 (bought empty OS), installed win 10 first and then installed Lubuntu 18.10. Got 'problem' which was boot straight to Lubuntu. Googled here and there.
Disabled secure boot in BIOS.
Now, I am able to dual boot by press Esc while boot to show Grub and added some windows config in Grub( Grub windows config provided below).
The issues that I have are more likely hassle and a suboptimal system: 1. Have to keep press Esc to go to GRUB. If not, system will directly go to lubuntu. How to show Grub without have to press anything?
Having to press Esc whenever I want to boot win 10 is just getting old.
2.In my win 10, inside shell command window running as Admin.
If I want to run bcdedit, I get error:
The boot configuration data store could not be found. The requested system device cannot be found
This should not happening right?
The systems I have with EFI Grub for windows all have a 'set root' line which points to the partition in Grub terminology or by UUID (shown below) which doesn't exist in your entry.
Quote:
set root='hd0,gpt1'
search --no-floppy --fs-uuid --set=root 00AB-33E7
Do you have a boot option key from the BIOS after using the Esc key? The entry you posted points to the correct windows boot file but doesn't tell which partition it is on so are you booting from and EFI files for windows or is it actually Grub?
The link below is to boot repair and using the 2nd option (ppa) is best as it is kept more current. Just run it with the Create BootInfo Script option without making any changes and post the link here.

Sorry I don't understand your questions.
In my system after presing ESc several times when booting, it will go to GRUB. To go to BIOS menu I have to user another key. IIRC F1 or F5, I forgot.
Yes,there's no setting UUID in my custom.cfg, does it matter? because I'm already able to boot and login to windows.

I don't even have that option (commented or set) in /etc/default/grub.
Here's mine, I remove commented variable for brevity.
It's somewhat surprising that Grub on Lubuntu did not detect your windows UEFI install and add it to the grub.cfg menu. According to the link below, the custom.cfg entries should show after the grub.cfg entries, not sure why it doesn't. If the change suggested above do not work, you might take a look at the link below. If you scroll down the page a bit, you will see a sample entry for booting windows 10. Try adding that to your custom.cfg file as it has several lines in the entry yours does not show.
wow..this actually works to resolve my first issue. Thanks a lot colorpurple21859. But I still have the 2nd issue, with the windows 10 command. I know this is Linux forum, but I just don't believe the solutions for windows 10 that spread in internet. They have the potential to break grub/linux bootloader. Anyway, I'll mark this thread resolved. Thank you guys.
But I still have the 2nd issue, with the windows 10 command.
What issue would that be? Are you trying to create an entry for Lubuntu in windows BCD? I don't think that is possible. See the link below at the neosmart site, the paragraph beginning with "What this means". Did some online research on this and didn't find anything to contradict it. Good luck.
(I should add that I could initially boot nothing but windows, as HP suggested F2 and there was no hint whatsoever that one needs to hit escape to mess with bios and the boot order)
Tried the solution with the commenting out the hidden part, no luck(on an HP laptop). So:
If I do nothing, windows boots
I I do Escape and then F9 to go to boot manager, I get a list as follows:
Boot Option Menu
OS Boot Manager
ubuntu
Slack
Boot from EFI File
up and down arrow sto change option, ENTER to select an option
Press F10 to BIOS Setup Options, ESC to exit
If I choose 'OS Boot Manager', Windows boots.
If I choose ubuntu, I get a grub menu.
If I chose slack, elilo is invoked to boot slack.
If I choose 'Boot from EFI file', I again get menus and can boot linux
So the point is getting 'OS Boot Manager' which is Windows to the bottom of the choices, so presumably the default grub is invoked(i.e. change positions of 'ubuntu' and 'OS Boot Manager'
Any ideas?
On the HP notebook I use, hitting Esc then F10 takes me to the BIOS with a System Configuration tab, Boot Options. Arrow down to OS Boot Manager and make sure this entry is at the top in Boot Options. With OS Boot Manager highlighted press Enter and you should see entries for windows, Slack and Ubuntu. Use arrow key to highlight the entry you want and then the F5/F6 keys to move order, F6 moves up, F5 down. You need to do this in the BIOS as doing it in the Boot Options (with F9) is a one time only selection.
That still doesn't do it. In BIOS->System Coniguration->Boot Option
OS Boot Manager is highligted, but enter does nothing, nor do left and right arrows.
F5/F6 move them up or down, but no way to get to the F9 menu.
BTW I have both Secure Boot and Legacy SUpport disabled. Do I need to enable Legacy Support? The way this is written is about supporting oldr windows
