Recovery from backup fails to boot

Thread needs solution

I have used TI almost from day one.

Yesterday I installed Windows 10 Anniversary update.

Deciding I did not like it I resorted to restoring from that day's backup.

Big mistake as my pc now fails to boot and Windows repair fails.

What di I do now apart from find another image backup app?

John,

Did you perform the recovery using "Rescue Media"?  Is your computer Legacy BIOS or UEFI?

Thank you ftrpilot.

I used bootable media and the pc is UEFI.

All I try fails to work. Windows 10 repair does not work.

At a loss as to why TI has let me down. Really miffed.

John

 

What error message do you get during the boot process?  Is it "Inaccesable boot device"?  If yes you might try allowing the Windows repair to run again.  In repair, select Troubleshooting, then select Startup Settings, then Restart.  Upon restart choose option 4 Boot Safe Mode.  If boot succeeds to Windows desktop then click on the power button and select restart.  PC should boot normally.

Thank you.

I have run Windows repair but I get a 'locked drive' message.

I am restoring to a SDD if that is any help.

John

The locked drive issue is due to Windows Fast Start feature. Basically fast start is a hybrid sleep mode. Because it writes data to hyberfil when you shutdown a Windows 10 PC this data is saved to disk by hiberfil.sys.  When you turn on your computer again the data is read from the disk and loaded in memory for a faster start.  In this state Windows locks the drive to prevent data corruption. 

 

That's all fine except when you perform a low level disk function like a backup you are  backing up the drive in this locked state.   To unlock the drive a restart of the computer is what is needed.   This is a different function than a reboot.   Performing the solution I offered if you can in fact start the computer in Safe Mode allows you to restart it and solves the locked drive issue.

Thank you for that info Enchantec.

If what you say is correct, and I have no doubt that it is, why is there no warning that the drive is in a 'locked state' BEFORE running the image backup? To be honest, I don't think SSD drive was in a locked state anyway. This is the first time I have come across 'locked state' in 20 years!

Surely an image of the drive should be just that, and restoring the image puts the drive into the same state it was in when the backup was made, i.e bootable. If that is not the case, what is the point of making an image backup?

John

John, we came across some very strange issues in the forums a little while back that were caused by this same problem where Windows Fast Start was involved and users were running the Acronis bootable Rescue Media when the system was actually in a hibernated state and then the backup image files made from this state disappeared after rebooting into Windows because the NTFS file system had no knowledge that they had been created.

The way around hybrid sleep / fast start state / hibernation is to reboot from Windows instead of doing a shutdown.  Reboot does force a full restart of the system without going into a hibernation state.

Thank you Steve

I do not allow my PC to go into a hibernated state (as far as I know) as I don't leave it running for hours on end - unless I am trying to solve a problem as I have now!!

John

John, please see webpage: How to Turn On or Off Fast Startup in Windows 10 which will help you check whether this option is enabled on your system or not.

Microsoft has made hibernate a function of the Shutdown command found in the power menu.  When you select Shutdown in Windows 10 the system enters the hybrid state I refer to.  For that not to happen you must disable fast statt, hibernation or both.  The restart option of the power options does shutdown the machine in a traditional sense before restarting it again.  Give the offered solution a try, you have nothing to lose!

Thank you both for your comments.

I managed to restore from a backup by using a EasyRE dvd which happened to have TI 2017 on it.  I used that for the restore.

However, in the BIOS there are two instance of "Windows Boot Manager" plus "Window Boot Manager Samsung SSD" plus "Samsung SSD".

"Windows Boot Manager Samsung SSD" is the one to boot from but I have not seen WBM before so any ideas what that is about?

Thanks again

John

 

PS I have now disabled Fast Boot and Hibernate as per the instructions in your link.

John, see webpage: What is the Windows Boot Manager (BOOTMGR)? for an explanation of this function of recent Windows OS's.

Steve

In the BIOS there are two instances of "windows boot manager" listed. Just that, nothing else.

Could I remove them and any idea of why they are there?

The drive I boot from is "windows boot manager,samsung ssd" but there is also another listed as "samsung ssd" which does not boot. Can I delete that also from the list?

Thanks

John

John, the boot manager options all come from the Boot Configuration Data store (BCD) and the way to resolve the multiple entries would be to rebuild this BCD store data.  See webpage: How To Rebuild the BCD in Windows which will take you through the process of how to do this.

An alternative approach is to download & install a copy of the free EasyBCD program and you can use this to edit the BCD data or to repair / rebuild it etc.  I use this myself and it has been great - so much so that I would happily pay for it if it wasn't free.  The program also allows you to make a backup of the BCD and restore that if needed.

Hi Steve

I have BCD on my PC as I have used it to create a dual boot system in the past.

This is what is in BCD boot settings now :-

There is one entry in the Windows bootloader.

Default: Windows 10
Timeout: Skipped
EasyBCD Boot Device: C:\

Entry #1
Name: Windows 10
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.efi

The top one is probably from when I was trying a dual boot system.

There are no other entries in BCD.

Thanks

John

John, I would still suggest taking the option in EasyBCD to rebuild the BCD store and see if the list changes?

I did that Steve. BCD deleted all my entries so I added back my Windows 10 install.

BCD created the boot info and now the ****** drive will not boot again.

My C: drive is now unallocated (and the drive letter had been changed).  Restoring from a TI backup won't work as part 4 is missing from the backups. How dids that happen? So I cannot restore from this morning's backup.

I am back to using the EasyRE dvd and am now running a recovery program to at least get the files back.

I have had it with TI.  It's just not robust enough.
