Unable to use F9 to reset ASUS G750JW laptop

I have an ASUS G750JW that I got about 1.33 years ago. I really need to do a complete reset of the machine for various reasons. I do not have a recovery disk with this machine. I have been told that I reset the machine and press F9 to go into a setup menu. Once there I am to use option to reset the machine (rather than refresh). However, when I do so I get an error message which says that a required partition is missing.

This machine came with Windows 8 and later updated itself to windows 8.1 automatically. Note that I have infact not tampered with the partitions on my machine. I have attached snapshot of how the hard drive partitions look like at present. I have put in another internal hard drive which is Drive F in the picture.

Now when the proper method failed to reset the machine I did some search and came across this on youtube https://www.youtube.com/watch?v=u0iEDk6n23k

I followed this method and tried to partition the drive D using easeus partition manager. However, when the computer restarts the software is unable to partition the drive and I get a message which says "message(8169) unknown error" and "there might be some error on operating partition.". I have done error checking on my hard drives and they are 100% ok.

How do I reset this laptop? Should I just get a generic windows 8 disk from somewhere and wipe out drive C completely?

Oh by the way, I have sent email to ASUS but have not recieved a reply even after 4 days.

sanguine_soul, what email address did you use? You aren't supposed to send an email, you are supposed to file a support ticket call a Technical Inquiry.

https://vip.asus.com create a login, register your laptop, file a Technical Inquiry.

If you RMA your laptop to Asus they can reload the OS.

Then you should, as soon as you get it, use Asus Backtracker to backup the recovery volume on to a bootable USB 3.0 16GB flash drive, and use that bootable flash drive to install the out of the box OS configuration onto a new HDD / SSD.

Always preserve your original HDD so you can the original OS / recovery available, don't over write it with a fresh Windows install. Disks are cheap, get a better / faster HDD/SSD and use that for a fresh install, or better yet an Asus OS restore.

You may be able to use the recovery partition on your existing HDD, if the partition playing you did didn't delete the 20GB recovery partition or 1GB recovery support partition.

Uninstall Asus Backtracker, and install a new one that runs under Windows 8.1 here:

Asus Backtracker for Windows 8.1
http://support.asus.com/download.aspx?SLanguage=en&p=3&m=Backtracker&hashedid=n%2fa

See if that will find / use the recovery partition.

Make sure when you create the USB flash drive with Asus Backtracker you disconnect any USB storage other than that flash drive, some have mistakenly selected a USB HDD and blown it away - be careful.

When doing an Auss Backtracker restore, you need to pull the other internal drive, including the original HDD, or they will get re-partitioned and erased - just like the new SSD/HDD before it the OS configuration is restored to the new HDD/SSD.

Please let us know how it works out 🙂

On the ASUS website, I used Home > Support > Email Us. Then I wrote a lot of things into the text box for problem description.

Right, so the only option I have now is to use the ASUS backtracker. As you can see in the image, I still do have that 20.01 GB recovery partition. Does this mean that when I use the ASUS backtracker, in the subsequent system reset, the recovery partition will not be erased by ASUS backtracker?

By the way, why is it that I can't just take a generic windows 8 disk and install windows that way?

sanguine_soul, you said you split the D partition, I thought the image was the before picture... look again now after splitting the D partition and see how it looks.

Asus Backtracker only backups up the recovery partition image into a bootable USB recovery flash drive, it doesn't have anything to do with F9 reset, so don't try that again. 🙂

Laptops aren't like desktops, you can do an install, but you will find it is time consuming to find the newest drivers and apps from Asus to download - some aren't offered, and even if you find them, you need to find the right way to stream the drivers into the install, and update them after the install.

You can only hope to have done as good of a job as the engineers at Asus that made the image to install, certainly no better.

If you are in a hurry, get another SSD/HDD and do the Microsoft Media install, and try to do it yourself, but don't burn the recovery flash drive bridge - erasing the original HDD will mean you would need to return to Asus for an OS reload if you find you need it.

Please come back and let us know what you work out 🙂

If you can boot into Windows, can you use the integrated option to reset the system?

Just to clarify, I tried to split the D drive as per the youtube video https://www.youtube.com/watch?v=u0iEDk6n23k but it did not succeed.

Is there a possibility to use SD card rather than USB stick with the ASUS backtracker? I have a 32 GB SD card but only a 8 GB USB stick.

sanguine_soul, try it, and let us know 🙂

So I was able to use the ASUS backtracker with the SD card, even though it seems to have treated the SD card as a USB drive. However, I was not able to boot from it. I tried changing the UEFI and secure boot options from the BIOS menu, but to no avail.

More days got wasted until I was able to go out and buy a USB stick. I used the ASUS backtracker and was able to reset the machine, finally.

Anyway, I have another question. What SSD works on this laptop? I have some SSDs in mind, atleast 512GB capacity, but am not sure if they will work on this laptop and if it will be possible to install windows 8 on such an SSD. Shall I have to use ASUS backtracker again?

sanguine_soul, yes you can use your new USB Asus Backtracker flash recovery drive to restore the Asus OEM Windows install to your new SSD/HDD 🙂

So far users have reported success with the Samsung Pro 840, Pro 850, Evo 840, Evo 850, Crucial M500/M550, and many others.

I would go with the 850 Pro with at least 512GB, or stretch and get the 1TB. I have the 512GB, and am finally running out of game/VM install space and need to migrate older items to an external USB 3.0 drive.

Be sure and remove all other drives from the laptop before using Asus Backtracker recovery flash drive to restore to the new SSD, otherwise the other drives connected will also get repartitioned and you will lose all your data - put the Original HDD aside to preserve the original install - you can use that drive if you ever need to send in your laptop for service - so you don't need to send in your personal SSD.

Please come back and let us know how it works out 🙂
