Hi people
I Installed Dual Boot
Windows and Parrot
but when i start like normal
I cant select the boot
And i cant see the grub menu
someone can help me My Original OS is windows 10
After starting the pc the screen goes gray for about 10 seconds and after that it only starts windows, and the GRUB menu does not appear
Well, just some hours ago, I did a fresh install of Parrot OS (v4.8) with Dual Boot System alongside Windows. Everything went fine, even grub loader got booted and currently using the OS.
Given your post, have you installed GRUB in the same partition as your hard drive? You might have installed the GRUB on the bootable media through which you installed ParrotOS.
Another reason maybe, you have deactivated or disabled Secureboot (need to enable if you installed on the UEFI system)
Well another option might be setting the correct root partition.
For that
Get a Live USB stick.
Open terminal after booting up into the live desktop.
Mount the root partition by typing /mnt and boot to /mnt/boot and hit enter.
[e.g. sudo grub-install –root-directory=/mnt –boot-directory=/mnt/boot /dev/sda]
You should replace /dev/sda with correct partition or disk. Now update grub by typing sudo update-grub.
Check if these works or not.
Another final option might be using windows bootloader, then booting into linux and then fixing the issues.
For that, open Windows then open Command Prompt as administrator. Then do the following commands serially.
