I have been using a lot of Linux/based distribution during my UG days. It all started with installing solaris on my 512MB RAM machine after an installation demo by CSE seniors(Krithika, Balachandran and others) . Then, I went on to Ubuntu, Fedora, OpenSUSE, Debian for reasons during my project work. Of all, my Favorite is Debian for their less memory or/and power consumption with simple neat looks.
During my PG days I installed Ubuntu 14.04 and were using for the past 2 years (almost). Now that I wanted to get back to my fav Debian and went into so many issues which I haven't faced during those days. Moreover, hardware/software itself got too complicated with BIOS/UEFI/Legacy mode/Safeboot/Fastboot/Win8/Win10.
Objective, I wanted to replace Ubuntu with Debian and still use it a dual boot alongside windows. Specs: Debian 8.4, Dell Inspiron 3000 series, I7, 8GB RAM
Initial steps
0. To live boot F12 key at boot, I have to choose boot from pendrive under Legacy option in boot menu options. In UEFI mode with safeboot OFF already.
1. Downloaded Debian with Mate desktop environment[DE] as I preferred Mate over other DE than cinnamon, current gnome, KDE, etc
2. I installed with manual partitioning. Formatted the existing ubuntu "/" and "/home" and then while writing to boot loader it said Ubuntu detected. OMG. windoz? :-/
3. I went ahead and completed. As I booted, I could see only grub prompt. However, when I live booted all my partitions are safe.
Errors and steps taken to resolve
4.
grub> ls
hd0 (hd0,gpt12) (hd0,gpt11) (hd0,gpt9) (hd0,gpt8) ...
It will list the partitions in Harddisk
5. Find out where "/" of linux files is installed by pressing "tab"
press tab after typing as below..
grub> (hd0,gpt11)/
/bin /boot /etc /opt /home /root /sys lost+found ...
you can figure out what for you, for me it is 11 here in this example. It is used below
6.
grub> set boot=(hd0,gpt11)
grub> set prefix=(hd0,gpt11)/boot/grub
grub> insmod normal
grub> normal
This will make the grub OS chooser window to appear. But it showed only Debian. Where is the windoz ? :-/
7.
Do the below in termial after login to debain
# grub-mkdevicemap
# update-grub
# grub-install /dev/sdX
If these 3 steps are complete then you are done!!
8.
find out X as below
root@warriorwithin:~# lsblk -f
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
├─sda1 vfat ESP CAE4-7B30
├─sda2 vfat DIAGS F640-9997

└─sda12 ext4 331172f1-2eea-4589-a5ef-c1ab2f4975e0 /home
X for me is "a"
9.
root@warriorwithin:~# grub-install /dev/sda
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
what to do now? :-(
10.
Check if /sys/firmware/efi exists if so then mount as below. And we know that step 8 ESP is in sda1 we will mount that in efi
root@warriorwithin:~# mkdir -p /boot/efi
root@warriorwithin:~# mount /dev/sda1 /boot/efi
11.
root@warriorwithin:~# grub-install /dev/sda
Installing for x86_64-efi platform.
Installation finished. No error reported.
root@warriorwithin:~#
All Done!!
Cheers
