Grub Customizer

Grub customizer in Dual Boot setup.

Asked by Mitali Gupta

I have a dual boot machine with windows7 and Ubuntu 22.04 LTS on it. I use windows bootloader at startup and then get into grub menu. The two oS are on logical partitions.

When I use grub customizer; I can change entries in the menu; time etc by clicking on save. I want to change the appearance of grub menu but it seems I have to choose install to MBR. my question is if I click that will it mess up windows bootloader? I want to keep that as the default bootloader.

Thanks.

More information is needed. Are you using old boot or UEFI? I guess old boot. Old boot is far less flexible than uefi. You should install GRUB in your Linux root partition (sda1, sda2 or sda whatever, not /dev/sda itself), but, if it's a logical partition, that should not work. Can you please specify which partitions you have? The output of "fdisk -l /dev/sdX" (X is usually 'a').

No; I already have the partitions and everything. It's old boot; linux is on sda5, and the dual boot setup works with windows boot manager starting first and Grub showing after. I was asking about using the grub customizer tool to change themes for the grub menu. I was worried it might mess with windows boot manager and try to make the grub as default boot loader. But I used it; did not install to grub; just saved the settings and it was fine. But thanks for taking the time to try and help. Very much appreciated!
