SSHD prevents multiboot install of Mint Linux with Windows 10

The two urls are as follows:

http://paste.ubuntu.com/p/8F75fVnysX/

(This I prepared before attempting boot-repair)

and

http://paste.ubuntu.com/p/Nzw3JDGwWv/

I somehow copied the note. But cannot understand the 2nd para (The boot files of ...)

Boot successfully repaired.

Please write on a paper the following URL:
http://paste.ubuntu.com/p/Nzw3JDGwWv/

In case you still experience boot problem, indicate this URL to:
boot.repair@gmail.com or to your favorite support forum.

You can now reboot your computer.

Please do not forget to make your BIOS boot on sdb (ATA ST1000LX015-1U71) disk!

The boot files of [Linux Mint 19 Tara] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

I again see Grub Rescue.

If this is with both drives installed and in their original boot order, do this at the grub resue prompt with the usb removed

Code:

grub rescue> set prefix=(hd1,5)/boot/grub
grub rescue> set root=(hd1,5)
grub rescue> insmod normal
grub rescue> normal

at this point you should see the grub menu, if so select mint and boot.
if not then continue with the following commands

Code:

grub rescue> insmod linux
grub rescue> linux /vmlinuz root=/dev/sdb5
grub rescue> initrd /initrd.img
grub rescue> boot

this should get you booted into linux
once booted open a terminal then

Code:

sudo grub-install /dev/sda
sudo update-grub

when asked for password use your login password
This should fix the boot problem

Wow, I will try these commands.

Though in bad shape, I feel this condition gave an opportunity to learn something new. I just feel buying an SSHD was a bad decision because after I boot with Mint, windows fails to load and I have to use the original iso to boot from, use fixmbr, rebuildbcd and then windows relents. But this again disrupts Mint.

Armed with your commands, I started my laptop, and booted from BIOS to look for 2nd hard disk (Linux does not appear in the bootloader featuring windows) and expected to see Grub rescue.

BUT now Linux booted just fine. (But I am not sure it will behave next time, because after every reboot, my laptop behaves differently)

Right now, I am typing this from within Linux.

Thanks for all help.

----------
BTW, do you know how can I transfer the bootloader to windows section so that I can choose whether to load windows or linux?

There is something wrong.

Windows bootloader should boot by default, but in its absence, Linux appears and Grub rescue is seen.

The commands insmod normal AND inmod linux says no such partition

(Though I get the linux bootloader only when I boot my 2nd hdd, from bios options (choose boot from USB/2nd hdd etc)

your windows bootloader was replaced by grub when the boot repair was ran. according to the last boot repair report:

Quote:

Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
for /boot/grub

core.img should be looking for (hd1,msdos5)/boot/grub, therefore the grub rescue.
If you want the windows bootloader on the first drive you will have to get a windows cd and run boot repair.

If you want to keep grub on the first drive, boot into mint open a terminal and run

Code:

sudo fdisk -l

that is a lower case L to make sure your first drive is /dev/sda(if not change the following accordingly), then run

Code:

sudo grub-install /dev/sda

. It that doesn't work then run the commands as I posted in post 17, If you get errors on the two set commands post the ouput of ls.
