View Full Version : ASUS G752VS Recovery Partition really necessary?

I'm about to reinstall Windows 10 on my G752VS that I've had for a week. I'm having all sorts of strange issues that a reboot always seems to fix but I'm rebooting every day. I know... First world problems...

Since I've had my laptop, I've uninstalled the bloat ware ASUS included and updated Windows 10 to the Windows 10 Anniversary edition. I've discovered that the ASUS Backtracker software does not work on Windows 10 (to backup the recovery partitions) and it won't even let me install it. In getting ready to reinstall Windows 10, I've discovered that booting pressing F9 does not work to bring me to the ASUS recovery (not sure if this worked before or not as I never tried until now). Yes the ASUS recovery partition is still on my SSD, but I'm wondering....

Is there any real advantage to keeping the ASUS Recovery partitions as opposed to just Installing Windows 10 as a clean install and wiping out the Recovery partition? I honestly don't see anything of value with the recovery partition other than the folder with all the drivers and utilities (which can also be easily downloaded from the website and installed as necessary).

With my other past ASUS Laptops that I've owned, I've always just wiped everything from the drive and did a clean install of Windows starting fresh and never gave the recovery partitions a second thought.

This thread which is a Sticky seems to back up my thoughts but doesn't really discuss the recovery partitions at all but indirectly says to delete ALL partitions: https://rog.asus.com/forum/showthread.php?76993-Guide-How-to-install-windows-8-8-1-10-The-proper-way-(UEFI-based-installation)

Am I missing anything of value in the recovery partition if I delete them? I personally don't think so but I just wanted to see what others thought about this.

Thanks in advance!

Even with a fresh install; Windows 10 automatically gives you a recovery partition. I've wondered the same thing too but for some reason it has its own purpose, just like the EFI partition. I say that because it only takes up 450mb of space to just leave it alone; you might run into all sorts of other issues; you can try to delete it but for only 450mb I'll just leave it alone.

please read my guide (about windows installation ) to learn more about MS recovery partition. ( in my sig you got a link )
about Asus recovery partitions... if it's many GB in size - it's your call... one way or the other after 30 days, you can NOT go back to windows 8 and your win8 product key is forever a win10 one.
thus, even if you'll install win8 once more, your win8 will not be legit any more ( AFAIK ).

Does it say "System Reserved" or does it use the word "recovery" somewhere? If it's the system reserved partition, you can delete it with the Windows installation. Windows will just recreate it.

If you have a recovery partition, maybe contact support and try to use that first. I thought about a clean install (I usually do one on a new laptop), but it isn't as easy as it appears anymore (see Gps3dx's guide). I did like you and just cleaned the bloatware off my new laptop, but then I haven't had any issues.

Hi there.

This is the way my SSD currently sits.


It sounds like you are saying that there is no ASUS recovery and that the recovery options are all from Windows 10. Is that correct?

If that is correct, then I'm gonna nuke all the partitions then reinstall Windows 10 from scratch and start clean like I should have.

I already have a Windows 10 installation USB key on standby all ready to go. Drivers are all on my OneDrive as well.

Thanks guys. I appreciate your comments.

Ahh, a picture is worth a thousand words in this case. You have a GPT disk instead of MBR, in which Windows will create those when it's installed. You must have upgraded at some point? I'm not sure how you'd have gotten two of them otherwise. I don't see an actual system restore by Asus on there. That's why I like to use Clonezilla after I remove the bloatware and grab an image the system.

In my opinion, you are safe to remove all partitions and start over. If you convert the drive back to MBR (you have format options available when installing Windows 10) you'll save about 300 MB of space, and have one less partition. There are no advantages to GPT on a disk this small. You only really need it when you have a disk larger than 2 TB.

I went and found this article to help explain it as I feel like I'm not doing that very well.

Quick after thought. Use a tool like Magic Jelly Bean to get your windows 10 key before you wipe the system. Depending on your install ISO, some older ones use to demand the key before moving on. It's just goo to have before you wipe it out :)

Hello again.

Thanks Buggsy. When I got my G752VS it came with a 256G SSD with Windows 10 Pro 64bit but I was not happy with the size of the SSD so I bought a Samsung 950 Pro SSD 512G and the place where I got it all from installed the 950 Pro for me and cloned the 256G over to it. So that is the physical upgrade that was done.

Software wise, the computer shop wiped the original SSD clean leaving me to boot from the new 950 Pro and the 256G SSD was empty ready for whatever I wanted to put on it. Once I got the laptop home, I booted it up and then in doing my Windows updates, the Windows 10 Anniversary edition was installed. Then I put on some games and played for about a week until I noticed the strange issues making me want to clean install.

I know that Windows 10 already has it's own recovery scheme but I thought that ASUS had put their own recovery partition on and was surprised that booting to F9 didn't work. Anyway, last night I booted from my Windows 10 Installation USB key and got to the point where I can delete partitions and this is what I saw:


Now I see another partition that wasn't visible before from Disk Management in Windows 10. Could this be the ASUS recovery partition? I wonder why the F9 at boot doesn't work for it. Would there be anything on there that I would need?

Thanks again guys.

I *think* that's just the bootloader. Another function of a GPT disk. With a standard MBR disk, you only get one 500 MB partition for system use and includes the bootloader.

I don't want you to wear your SSD more than needed, but maybe you should do a secure erase of it. It's like the old "low level" format in a way for SSDs. It would reset it to a factory-fresh state with no partitions at all. I can agree that something may have happened when they copied your OS to the new SSD. It's odd to see two restore partitions, and I wonder if this drive was brand new or possible used.

partially correct... the MSR partition is not for the bootloader... that's why the "efi"/"system" partition is for...
MSR is a partition that you MUST HAVE on a GPT layout formatted drive, and it is responsible for "GPT" related maintenance.
Please refer to my guide about" how to install windows - the proper way" to understand better about the various partitions GPT layout MUST have, and what MS windows creates ( see my sig for a link) - which are 2 different things.

Lastly, since you start from SCRATCH ( please note the SPECIAL method if you CLEAN upgrade win8->win10 - you can read about it in the same guide I mentioned above ) - you can do indeed wipe all of that drive. ( BUT I warn you again -pay attention for the SPECIAL upgrade method if you perform for the 1st time the upgrade from win8->win10 ).

Thanks Buggsy and Gps3dx...

I think your right about the partitions and I'm going to wipe out all the partitions tonight when I'm home from work and reinstall Windows 10 Clean. I've been going through your guides Gps3dx and they are very handy. Great job! I'm not sure exactly what section your referring to though when you say "Special Upgrade method" as there are so many parts. However since my G752VS came with Windows 10 as default, I don't believe that your special upgrade method from Windows 8.1 would apply to me.

Hello again.

Just wanted to post back as a follow up to my Windows 10 Pro install on my G752VS with my Samsung 950 Pro 512G.

The install went very smooth. Windows 10 Pro was installed in 8 minutes! Here are my partitions in case anyone was curious.


There were only a couple of slight hikkups.

1. Had to change the SATA mode in the BIOS from RAID to AHCI to be able to see the drive before I could delete the partitions and install Windows 10 Pro.

2. When installing the Audio driver, it went into a unending loop of uninstalling the default audio driver, reboot, installing the new audio driver, and reboot. It did this about 6 times before I had enough and hit cancel. Fortunately, my Audio is working just fine. Also, the Sonic Studio 2 is not installed with the Audio Driver. It is a separate install. Fortunately I saved the eSupport folder that came on my C: drive from the factory before I wiped my partitions and it was in there with all the other drivers and utilities. I haven't found where to download this yet though if I ever lost this but I'm good for now.

As to how things are working... I'd say pretty good at this point but it's too soon to tell. I'll give it a few days and see how it goes and play some games.

Thanks again for everyone's help.

Personally I leave the recovery, I don't condone clean installs, wast of time IMO. My offer for anyone to prove they can outperform my updated versions with recovery still intact with a clean install still has no takers.

Now for a MAJOR problem with the above picture, you have ZERO over provisioning on an SSD. This spells certain disaster! You should have 10% of that drive unallocated!
It has to have extra for trim to heal itself.

Note my SSDs

Hi JustinThyme.

Thanks for your post. I appreciate your feedback.

The screenshots that I took were all (with the exception of the photo of the Windows 10 Setup showing additional partitions) from the Windows 10 Disk Management utility which does not show MSR partitions, if that is what you are referring to. I'm sure the MSR Partition is actually there as I used the UEFI/GPT installation steps but I'll have a look with diskpart when I get home to make sure.

In my case, if the recovery partition was even there, it wasn't working at all. Pressing F9 at boot did nothing. Plus, no one could tell me what benefits there were to trying to save it. I already had the "esupport" folder with all the factory drivers/utilities backed up. I could however go into the Windows 10 recovery options and use Reset this PC however I choose to clean install with a USB key instead which is not a big deal.

I had Windows 10 reinstalled in 8 minutes from the deletion of all the partitions back to the desktop. Reinstalling the drivers/utilities took about 30 minutes after that, mainly because I was taking my time. Then Windows updates... Then reinstalling my games. Keep in mind that most of this would have to have been done anyway even if I had used the Reset this PC option.

Everything, so far, is running very well now.

Like I said, when I get home from work, I'll have a look using diskpart to ensure the MSR is there.

Hello again.

Looks like all the partitions are there and I'm in good shape.


Thanks again.
