Dual Boot from different hard drives


I have a Windows 10 laptop and just added a second hard drive for Linux Mint. Can anyone help with the set up of dual boot where Windows 10 boots to first drive C: and Linux would boot to the second drive F:. I found several samples using one drive but I would prefer to use two drives. they are both SATA drives.

if you are suggesting that you are going to use the second hard drive as a linux os. then just partition that hdd as if you where not doing a dual boot.

but remember that before you start to install linux. that you pick the correct hdd for it to install on. I'd guess it would be /dev/sdb1

then when you get to the end where it asks you about the boot loader. Grub install it on /dev/sda MBR if you are doing this new UUID thing referr to someone esle that is using this method of booting....

I thought that that would be the way it go but I was not sure and I am very new to Linux and I can not afford to mess up Windows 10. To much time to reinstall and setup again. Thanks for the help

the way you are doing it is good, hum, you won't mess up windows but if you want to be on the really really safe side. you should find a rescuse disk, or if windows still creates one make on that you can use to repair MBR and boot someting I forget what it is called. you can then fall back to that if you have to, to over write grub in order to just boot into windows, without linux.

I had a install CD to get into that with was two simple commands in the window rescuse screen might want to google it first. one was fixmbr I forget what the other command was.


but yeah, depending on the size of your second HDD if you want windows to use any of it then partition it and do not use it. after you get done installing Linux on that hard drive then you can set it up as ntfs that way both Linux and windows can share it.


but if grub messes up for whatever reason. Me personally ~ it is faster to just do a new install of linux, partitions are already set up, just have it set the way it was formatting your /

because, seeing how you have not really set linux up then just reinstall grub over top the old one. as most people spend much time in help me fix this when if they'd just reinstalled it that would have been faster in a long run.


I'd suggest partitioning as follows.

Quote:
/dev/sdb1 swap
/dev/sdb2 /
/dev/sdb3 /home
all primary
if you save left overs for sharing then it'd be extended partition.

ah the ole auto set partitions for me selection.

depending on the distro install program. Some have this selection, then it depends on how you select to partition it. 1. with everything on root -> /
or
two partitons root / and home /home

it will make a them for you then ask you if you are ok with it. if yes then say yes then it will get on with it.

else you can go into manual mode where you tell it what it is you want.

if you like the auto selection that it picks for you. Then select ok and let it write it to the hard drive and get on with your install.

even afterwards:


You can still take it after it is installed using gparted (the easiest MO) then resize it and split it up afterwards. it is a little tricky. but not too bad, depending on what it is you want to do with it. but it can be done.

actual root does not really need a lot to hold the OS and apps.

I've got mine set to 75GB and loads of stuff installed and only using 27% of the 75GB.


the limits would be how you partitioned it prior to.

with gParted just right click on the partition and select resize.
it shows you a line graph.

Code:
swap 1GB?     / 5 to 100GB   /home the rest of it??
begining <==========================================> end
1 TB
then you can just slide it one way or the other depending on what it is you want to now do with it.


you can push from the front of the /home making your / root bigger. or srink your /home by pushing the back end forward then partition that and make it ntfs to share between windows and linux.


or you can srink root causing it to make home bigger.


if you just go with swap and /

you got all of what is not swap to play with and you can split it up and set partitons for any of the directories, such as you can do this with the first senerio too.

but most people go with two partitons and a swap, unless they want to play maga server dude.

Gparted will move any data that is in that section of the hard dive then reestablise boundries.

none of this will take place completely until you click that arrow. you can always cancle what your looking at. same with a manaul partitoning before you install.

it will not take effect until you write it to the hard drive.

but if you wait until you've installed a bunch of stuff and loaded up your home, this just means it has more data to deal with to try and move it to get the size partitions you now want ( at a later date).


I am sure I have just confused you more.

but you have options. even with Windows you can go in there and open up the hard dirve manager and resize you hard drive. limits for the most part are the none moviable data (in windows) and in Linux from my experience, it just takes longer as it moves data to resize the partition.

it is better to just read everything and go manaul .. if your using Ubuntu or clones then they have a selection that says ' something else' that is where you can manually set up your partitons.

just take it one step at a time slowly making sure you get the right size you want, then select mount point and file type and that little check mark on the line that says what partition it is , is check for formatting.

it is rather simple for the brave hearted.

as you are doing this on a seperate hard dirve I'd not be too scared to try anything with it. you are not dealing with windows that is seperate. Just besure when it shows you a partiton you are looking at your second one
/dev/sdB and not /dev/sdA for everything other then where it is going to install grub.

/dev/sdA


if you're doing a desktop master / slave the master is Windows and slave Linux until you install grub. then Linux is master

lol

but yeah.
hdd 1
/dev/sda windows
hdd 2
/dev/sdb linux

You don't indicate whether windows is UEFI/GPT. Pre-installed it almost surely is so you would need to install Mint UEFI/GPT or one or both systems will not boot. Take a look at the link below for some basic info on this.

windows is most certainly a UEFI and it is giving me problems to dual boot. I am not sure how to fix this problem. The UEFI can not be by passed. I can change to enable legacy boot but the bios still uses legacy as second in priority for boot EFI has priority. how can this be fixed.

Having an MBR install with a UEFI install means you won't be able to boot one system so you should not install Mint MBR. Mixing the two doesn't work. Did you read the link I posted earlier to the Ubuntu documentation on dual booting UEFI? Did you install Mint yet? My understanding is that you should have an option to install UEFI or MBR on booting Mint but I don't use UEFI so haven't tried it. You might try getting the boot repair software from the link below using the Mint installation medium. Select the option to Create BootInfo Summary and post a link to the output here and do not try to make any repair.

linux is installed as EFI boot. that i have confirmed. its just setting the boot options menu so that does't take so many steps and must be done manually or Windows boots auto. the boot option must be invoked manually.
