Thread: can a ssd have a mbr and bootloader?

i install both linux , windows on newly bought ssd(sda)
and when installed linux, chose install bootloader on ssd(sda).
after finished, got black screen when chose boot ssd,
but strange thing got grub menu when chose boot hdd(sdb),
and i'm sure chose ssd bootloader installation location.
so why did bootloader transfer ssd hdd?
does mean ssd can't hold mbr or bootloader @ beginning of it?

i boot ssd without issue.

sure installed ssd? grub likes default sda , drive order not fixed.

can reinstall grub inside install, confirm sda , sdb. example uses sdb, change sda if needed.

#reinstall working (not livecd/dvd/usb) system - first find ubuntu drive (example drive sdb use drive not partitions):
sudo fdisk -l
#if it's "/dev/sdb" run:
sudo grub-install /dev/sdb
#if returns errors run:
sudo grub-install --recheck /dev/sdb
sudo update-grub

maybe should anyway. grub on major update may reinstall wrong drive , not sure above install method resets that.

#to grub2 remember reinstall on updates:
sudo dpkg-reconfigure grub-pc
#enter thru first pages,spacebar choose/unchoose drive, enter accept, not choose partitions

check before & after first set of commands above see if reset reinstall drive.

#to see drive grub2 uses reinstall see line - grub-pc/install_devices:
sudo debconf-show grub-pc
sudo grub-probe -t device /boot/grub
