Acer Predator 17 (G9-793)_Raid 0 failed_"NO BOOTABLE DEVICE" error

nikhilsjoshi

I have an Acer Predator 17 laptop (G9-793) with a 256 GB in Raid 0 configuration (Two 128 GB SSD). One of the 128 GB SSD (port 0)was showing status as Failed in the Intel Rapid storage technology. I ran the system scan on the Intel website. It asked me to update the Intel rapid storage technology interface. I did it and then restarted my system as prompted, but then I got an error "No Bootable Device".
After that, following troubleshooting optioned I tried:
1. Using Advanced repair options I tried to access system restore but I am unable to open it. It is displaying an error: 
2. Using the CMD in advance troubleshooting options I tried to run DISKPART but its is not showing the two 128 gb SSDs, it is only showing one HDD I have.
3. In the CMD I can see that the "c:\"  drive has been changed to "x:\", I don't know how this happened. 
4. In the UEFI boot menu it is showing both the SSDs. But unable to boot. I restored the BIOS Settings but it didn't work.

My questions is how do I resolve this issue. Do I need to send the laptop to acer for repair? How do I copy all of my data using CMD to an external Hard drive? 

Also if any one can help me with how to change the drive letter from "x:\" to "c:\", this might work. 

Please help.

Thank you,

nikhilsjoshi i suspect by what you said abovethat one of you ssds died and because it was all in raid 0 (which its the worst raid you can create if one dies you loose everything) your only option now its take both drives out and test them both in another system to make sure one is really dead and if this is the case put the working drive back and reinstall windows from scratch clean install this is the only options i see here

And no you cannot copy any data from a broken raid 0 array the only way you are able to recover your data its spending thousands and pay a recovery company to use a donor drive to bring back the dead one to live and rebuild the array to recover the data if youre still on warranty send it to acer for a new drive replacement but barre in mind you data is long gone by now

I think you didnt understood the meaning of raid 0 raid 0 means all data its split in bits/parts on both drives you will never have one single file in one drive only they are all split making it a bit faster because it writes on both at same time but the big downside here its if one drive dies its bye bye to all no way to get it back period unless of course you pay thousands as i said above but i doubt the data you had there its worth thousands to recover usually only company's use the recovery services for data recovery because its way too expensive so my advice to everyone who might read this never ever use raid 0 if you want to use raid use raid 1

• RAID 0 – striping.
• RAID 1 – mirroring.
• RAID 5 – striping with parity.
• RAID 6 – striping with double parity.
• RAID 10 – combining mirroring and striping.

xapim, Thank you for your help,
Yes, luckily my laptop is still under warranty. This all happened when I updated iRST interface and drivers. One of the disks in Raid 0 was showing failed but it was working fine until I updated the iRST interface. After that, it was completely inaccessible. I am sending it to ACER for repairs. 

I have one more question about  Upgrading SSDs. Can I remove both the SSDs which are in RAID 0 config. and install single 1TB ssd and install windows using the media creation tool? will it work? will it affect BIOS?

Thank you again,

nikhilsjoshi yes you can remove both ssds and install only 1 drive just change the option in the bios (if any im not sure which options you have in your bios ) from rst to any other available as i said raid 0 its not a good option at all unless you make periodical backups of everything
