Dual Boot (with Win 10 and Linux)

Oct 31, 2016 9:33AM PDT

I want to dual boot Windows 10 and a version of Linux (most likely Ubuntu).

Ideally, I would have 3 hard disk partitions
1. Windows 10
2. Linux
3. Data Storage

First off, is this a good or bad idea?

How large should I make the Win10/Linux partitions?

Lastly, how can I make it so that both OSs can read/write to the data storage partition?

As far as I'm concerned
Oct 31, 2016 9:43AM PDT

I see no reason to dual boot these days since I can create a persistent flash drive using ubuntu and I can make the Casper partition as large as I want.

I dual booted for a couple of years but why would I want to mess with my hard drive these days ?

Well sometimes I don't really want to carry around a flashdrive in order to boot to my desired OS. I can see the merits of doing so, but, like I said, that's just not for me.

It's technical but your 3 partitions are a failure.

Even if I don't write about w10, Linux needs at least 1 more partition since forever. When I setup my dual boot Linux (which I no longer do anymore and will share what I do instead) I leave unpartitioned space so the Linux distro's installer can set it up for me. Only the very very advanced users partition then install.

So what am I doing now?

1. The method I noted.
2. VirtualBox and install the Linux there.
3. Some USB sticks. My favorites to carry are:
b. Ubuntu.
c. Puppy.

A, b, and c each have their reasons.

Yeah, but...

It's just not the same to use Linux through VirtualBox. I have tried multiple Linux distros via VirtualBox (including Puppy and Ubuntu), but I just don't really like it...

This is your choice to make. My point is that the partitions needed are more than three.

But it's a great way to learn about OSes, partitions and backups. That is and I didn't note it, the number of folk I've helped recover their PC that installed Linux, deleted Linux and then couldn't boot anything is legend.

Well most VB Linux installs

for me would not let me use the full potential of my graphics card except Mint. It allowed me to use 1920 x 1080 resolution. Another thing is you have to give the VM enough resources like memory and drive space. I give 8 GB since I have 16 gb in my machine.

cvt & xrandr can fix that
Nov 1, 2016 11:12AM PDT

I added this to my .xprofile file in my user's home folder.

xrandr --newmode "1600x900_75.00" 151.25 1600 1704 1872 2144 900 903 908 942 -hsync +vsync
xrandr --addmode VGA-0 1600x900_75.00

Because it was not available, and I wanted a lower resolution for my 1920 x 1080 TV/Monitor I'm using now. You can change the settings also to allow full resolution. You can add several of the lines and then have them all available in the Display Settings area.

Remember to first run "cvt" command to get your modeline.

cvt 1920 1080 70

the last number is desired refresh and some can run 70 but may need to use 60 instead. When I run it on my linux mint computer using 60 refresh, this is what I get.

cvt 1920 1080 60

# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz

Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

Here's an interesting thread on how to do it at linuxmint.

Seemingly, instead of a more involved older way, you can add numerous resolutions using this easier method or "trick" and avoid those messing around with those PIA xorg.conf file settings.

it really depends
Oct 31, 2016 2:37PM PDT

microsoft made it a bit difficult to dual boot these days because of UEFI. it made it too easy to mess up. If you never ran linux before, it would be best to stay away from Ubuntu and use one of its cousins like linux mint. Ubuntu has unity and unless you know the names of the utilities you want to access, it is difficult to use.

one final thing, before trying to install a dual boot, it would be best to create a clone of the drive in case you mess up.

Possibly unwanted advice
Oct 31, 2016 5:53PM PDT

If this is a laptop, leave the original OS intact and use external media for Linux. If this is a PC with Windows 10 already installed, leave it alone and add a second hard drive for your Linux distros. When installing these, disconnect the Windows drive so the installation won't interact with it. Do your multiple boot by selecting whatever boot menu key your BIOS offers rather than use grub or some other bootloader. I know this isn't the cool way to do things but I find it to be the safest. Knowing that, with boot failures, it's not a matter of "if" but "when", don't risk a problem with one OS taking out your whole system.

I tend to agreed.

For the extra cost of a Hdd. one might save lots of headache, and if the board is like a couple of my Asus board, a boot menu comes on every time the computer boot up. So it's only one key stroke more than dual boot.

I think if one already has a windows drive
Nov 1, 2016 11:19AM PDT

setup on the computer, then probably a 32 GB USB flash is more than enough, since files from Linux can be saved to a folder on the windows partition if more room is wanted. However on windows 10 with UEFI, unless that Linux is also UEFI capable, the newer BIOS may still isolate the windows portion of drive and not allow it. That seemed to be the case on my FIL's windows 10 computer on a visit when I used it in Legacy mode to boot a 32 bit non-UEFI linux DVD from it. I didn't try an 64 bit UEFI version of linux to test that on the windows drive since at the time I wasn't trying to access his windows disc, just use his computer for my own internet access.

I have no issue with flashdrive but...
Nov 1, 2016 2:03PM PDT

OP doesn't like the idea. In fact I have all my distros. on's so easy to do but I guess OP is really doing some serious work with Linux.

USB 2.0 or USB 3.0 makes a difference
Nov 1, 2016 5:05PM PDT

in how usable this media is. My rig has only USB 2.0. I've a couple of Linux distros, including Tails, on USB but installing and using them is painful when compared to those I have on SSDs. I've a number of older, smaller mechanical drives around and these serve well for testing Linus distributions. Flash drive installations are for when traveling.
