After a lot of research and personal experiences I've come with the perfect fix, You'll not gonna find it anywhere.
grub> ....... Now type in .......
grub>ls ....... if your boot system is uefi(considering you've chosen all files in one partition while installation otherwise a lot of them) you'll see.......
grub>(hd0) (hd0,gpt5) (hd0,gpt1)
grub> (hd0) (hd0,msdos5) (hd0,msdos1)
....... so, now we're gonna have to load the kernel and the initrd image, usually the kernel files lies in the boot folder inside of the root folder in my case it's (hd0,msdos5). So if you're kernel files are inside the root or the linux partition, it's good else stay with me.......
.......let's start by checking(partitions can also be denoted by hd0,X --X is your partion no let's say for(hd0,msdos5) you could write hd0,5) .......more details at the end of the tutorial.......
grub>ls (hd0,5)/grub>lost+found/ bin/ boot/ cdrom/ dev/ etc/ home/ lib/
lib64/ media/ mnt/ opt/ proc/ root/ run/ sbin/
srv/ sys/ tmp/ usr/ var/ vmlinuz vmlinuz.old
initrd.img initrd.img.old""""""" (let's see inside boot)
....... type in .......
grub>ls/(hd0,5)/boot/ bash grub> grub/ system.map... vmlinuz-4.19.37-parrot1-amd64... initrd.img..... and so on .....(if it's there then its ok other wise
you've to look inside(ls) the other directries. In my case the kernel files are inside (hd0,1) .......
....... Now let's discuss the normal scenario in which the kernel files are inside boot of your linux partition....... ....... if your kernel files are in other partition scroll a little down and continue from the hint of stars .......
....... type in(Optional) .......
grub>set pager=1....... Now select your root partition or your linux installation partition .......
grub>set root=(hd0,5)....... Now it's time to load kernel which is inside boot directory. so the kernel file name starts with vmlinuz i'm writing mine make sure you write yours .......
grub>linux /boot/vmlinuz-4.19.37-parrot1-amd64 root=/dev/sda5....... root part is optional but sometimes pc gets a kernel panic so it's better adding it .......
....... now its time to load the initrd image check the name with initrd.img and write it without mistake. I'm writing mine .......
grub> initrd /boot/initrd.img-4.19.37-parrot1-amd64....... done now you can boot .......
grub>boot
.......Now if your kernel files are in other partition instead of linux partition/boot then you've to set that partition as root temporarily. other wise you can't load the kernel by just mentioning it's directory. Stay with me.......
.......In my case my linux partition is (hd0,5) and my boot partition is (hd0,1) and my kernel files were inside the (hd0,1) partition . So let's fix it.......
grub>set pager=1 (optional)
grub>set root=(hd0,1).......Now it's time to load kernel which is inside it. so the kernel file name starts with vmlinuz i'm writing mine make sure you write yours.......
grub>linux /vmlinuz-4.19.37-parrot1-amd64 root=/dev/sda1.......root part is optional but sometimes pc gets a kernel panic so it's better adding it.......
.......now its time to load the initrd image check the name with initrd.img and write it without mistake. I'm writing mine.......
grub> initrd /initrd.img-4.19.37-parrot1-amd64
**.......now let's change the root directory....... **
grub>set root=(hd0,5)Disclaimer-- if you find it long then you can do,
linux /boot/vmlinuz-4.19.37-parrot1-amd64 root=/dev/sda5 after setting the root to (hd0,1)
....... you're done now let's boot .......
grub>bootImportant after the system boots follow this tho fix it permanently. fire up terminal and type .......
sudo fdisk -l
....... check the name of your drive and type......
sudo grub-install /dev/sda
sudo update-grub
Congrats you've fixed it....
Finally and most importantly, never ever give up and don't let the pain blind you.
