Dell Ins 2350 AIO upgraded to Windows 10. Had Power failure while shutting down computer. When trying to reboot, computer posts:
No Boot device available
SATA1: Installed
mSATA: None
F1 to retry F2 for setup
Did ePSA diagnostics, all hardware passed, Tried backup and recovery usb drive, computer booted to drive, tried the 5 minute repair, could not repair partition. I do not want to lose all my data by reformatting and replacing the system.
 
tsnor, I am new to this forum, or any forum for that matter, and I really appreciate you responding. I downloaded mini-tool partition wizard, and made boot usb disk. Your link was very helpful.
This is information using the Mini-tool Partition Wizard Boot Disc 9:

Partition Capacity Used Unused FileSystem Type Status

Disk 1
*: System 99.98 mb 29.54 mb 70.44 mb Fat32 GPT (EFI System Partition) Active and Boot
*: System 128 mb 128 mb 0 B other GPT (Reserved Partition) None
*: OS 918.15 gb 576.75 gb 341.40 gb NTFS GPT (Data Partition) System
*: 450 mb 357.34 mb 92.66 mb NTFS GPT (Recovery Partition) None
*: PBR Image 12.35 gb 11.75 gb 620.57 mb NTFS GPT (Recovery Partition) None
*: 350.00 mb 289.48 mb 60.52 mb NTFS GPT (Recovery Partition) None
*:
*: Disk 2
29.82 gb 0 B 29.82 gb Unallocated Logical None

Disk 2 is a mSata Samsung SSD PM83 which was used as a cache disk. I tried to perform the Partition Recovery
Wizard on this drive with no success. Does anyone have any suggestions as to what all these partitions are for,
and how I get my computer to working again. I am not sure what the GPT type means either. Any help will be
greatly appreciated.
 
Windows uses a lot of hidden partitions for booting.
The top partition, 1/10 of a GB =100 MB, is for boot code.
The third partition, 918GB is where all your data is.
The fifth one looks like where Dell hides the recovery boot image for your PC.

If you can boot using a windows recovery disk or USB then maybe you can save whatever data you really don't want to lose from that 3rd partition before trying anything else.

Then try your choice of another partition repair tool, or attempting to boot yoru recovery partition and seeing if it can repair / refresh your PC without doing a complete format/install./

This one looks promising, but I have not tried it. Do any data copies to USB first if you can. http://pureinfotech.com/repair-master-boot-record-mbr-windows-10/
 


Would the mSata SSD drive have anything to do with not being able to boot? I don't have the OS on it, but it doesn't even show it as being partitioned. How do Cache drives work? If I do have to reinstall Windows10, I would like to replace the mSata drive with a 500GB mSata and put the OS on that if I can, hopefully saving my data on the SATA 1 Tb hard drive, is that possible?
