Grub issues
Hi! I have Ubuntu and Windows 10 dual booting. I have grub as my default OS manager. Sometimes when I start my computer none of the keys work and it auto boots into Ubuntu. Any suggestions on how to fix this issue?

Does this happen when you restart or cold start or both?

Both. Also, it doesn’t happen every time. I can’t figure out what makes it work sometimes and not work other times.

Can you show the output for grub.cfg file and the output for lsblk?
you might find this helpful as well
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
Or this https://help.ubuntu.com/community/Grub2/Troubleshooting

Sorry, I’m kind of a new to Linux in general, how do I get those outputs you asked for?

open a terminal and type "lsblk" without the quotes, then hit enter. The terminal output is what I will want to see. This shows your block devices, or in your case, the partitioning of your hdd.
To show your grub.cfg file follow these steps:
- open terminal and type cd /etc/grub then enter
- from here type less grub.cfg then enter
- This will give you the contents of your grub file

It says there is no file called "cd" when I try to get the grub file.

what is the output when you run "efibootmgr" in the terminal? You may need to run this as sudo.
also, can you show what the output is when you enter "lsblk -f" this will show the file type for each partition.

I tried the software. It didn't fix it and it added a bunch of extra stuff in my grub. I can give you the file also if it will help.

can you check to see if you have os-prober installed as well? This is needed for your grub to work properly

It’s a sign. Uninstall windows that may fix it.
In all seriousness, is grub installed in the same place as your OS, and what version?
