    Thanks, venom. I've read (and tried to understand) a good bit about dual-booting, and the inherent problems led me to think if I could just switch hard drives, I could avoid a lot of conflicts (and nefarious Win 10 updates).

    Can someone address the topic of switching drives, as opposed to dual-booting?

    If you switch drives, you will have no problem... You will want to have them both using legacy boot, or both using UEFI; if they are different, you will have to toggle that in the BIOS every time you swap drives. (Linux Mint works fine with UEFI in my experience... I'm not sure about with Secure Boot enabled though — and I honestly don't use it much anymore now that you can run a pseudo-Linux instance from inside of Windows on later versions of Windows 10, I find that it suits my needs just fine.)

    You could have both drives installed together (one mSATA and one 2.5"?) and just use the F12 menu at boot time to decide which one to boot up. You would want to have them installed individually when setting up each OS initially to make sure that each OS's boot stuff only lives on one drive. I don't think that upgrades on either OS would cause you any grief in this scenario.

    It should be possible to have both OS's happily sharing the same UEFI boot partition, and you would be able to select the OS from the F12 menu at boot time... UEFI is designed to support this, but I've never tried to set it up with dual-boot before.

    I dual-boot Ubuntu and win 10 on the same HDD for my desktop but seperate drive in my previous thinkpad x230 with UFEI, everything is smooth.

    Last time I set win on HDD on caddy Bay for hotswap, Ubuntu on msata, swap is easy without trouble, but not when I try Uefi, I haven't found the reason yet

    Personally, I recommend Legacy for better hardware - software "cooperation", may be its just my m4800

    This is how I've done it in the past, though I had another 2.5" SSD in place of the optical drive, rather than using an mSATA.

    Hello All,

    Just wanted to inform you guys about fact that Dell Finally admitting (what I have discovered 3 years! ago) on my own. I spoke about it here on the forum. there is a second vulnerability that is being used currently and it relates to drivers (bridge) but proving it will be difficult as most likely its done by someone who writes them. "it" (not he she) selling out to shadow circle of "friends" that share the vulnerabilities across the industry including Routers.

    Hackers managed to steal my data and expose it. again knowledge of this brought me to think all systems are vulnerable to low level hardware attack and only ip v6 + firwall +VPN, somewhat can mitigate this, but at some point driver comes out and fishes all needed to penetrate again. those who know what I'm talking about will understand. (anti-virus is a placebo in such cases and only slows the application level attacks)

    its not about catching terrorists/bad guys whatever, its all about data hoarding. and to do that you must create reason and issue. (my own opinion)

    Have done exact same thing, its easy to swap, and also you can use Esata port as 3rd sata via adapter some cost 2$, and avoid drive headache.

    I have tried M2000M it works on 1080P boards and needs special VBIOS to work on QHD variants. (note it may also need same firmware to work on 1080P) hope it helps

    one importat thing Laptop boots from cold and reboots 5 times subsequently recognizing its parts CPU,GPU,Board<screen so when you have started wait and let it start/shutdown/start/shutdown ect logo appeares on 4th 5th boot (dell technicians dont know this and replace boards 2-3 times

    Why is this about Dell admitting something, when it's Intel's tech and they're the ones who admitted there was an issue 5 months ago (in May)?

    I understand you were hacked, and that's terrible/not something I'd wish on anyone, but this seems more like Dell-hating arising from frustration, rather than real wrongdoing on Dell's part. AFAIK no OEM released any fixes/BIOS updates until Intel published the problem. It's certainly fair to take issue with the speed (or lack thereof) with which OEMs address the issue, but I'd argue this puts Dell squarely in the middle of the pack (some released BIOS updates very quickly, some still have not).

    I have currently 32G of RAM in my M4800, however I do not cross more than 20GB during my usage (i.e the Max).

    I recently bought a notebook which came with 4GB RAM and can be upgraded to 8GB (bus speed same as M4800), if I remove an 8GB RAM from back slots of M4800 leaving one 8GB in the back slot and leave the 2 8GB's under the keyboard, with this configuration of 24GB on M4800 will there is any issue?

    I think the only issue is you will lose symmetric dual channel, but the system will likely default to asymmetric dual channel.
