Hi all, I hope someone can help with this Windows 8 Boot issue, apologies for the long post but I have tried a couple of things and tried to include as much information as possible. Issue When trying to boot Windows (no USB drive) I get: Legacy Boot Mode, Secure Boot Off Reboot and Select a proper Boot device UEFI Boot Mode, Secure Boot Off Windows logo followed by blue screen UEFI Boot Mode, Secure Boot ON Windows logo followed by blue screen (not a BSOD, just a blue screen) When I boot from a Windows USB drive where I get: USB1 UEFI >Repair Options >Troubleshoot >Refresh your PC Starts but does not get past 1%, then "There was a problem refreshing your PC. No changes were made" Advanced Options >Startup Repair "Startup Repair couldn't repair your PC" Log file: C:\Windows\System32\Logfiles\Srt\SrtTrail.txt Last line "Boot status indicates that the OS booted successfully." If I Change boot mode to legacy USB Storage Device >Troubleshoot >Refresh your PC "The drive where Windows is installed is locked. Unlock the drive and try again." I can get to a command prompt and see my data, Diskpart shows the following information: Diskpart Disk### Status Size Free Dyn Gpt Disk 0 Online 119GB 0 B * Disk 1 Online 7385MB 0 B Volume ### Ltr Label Fs Type Size Status Info Volume 0 C NTFS Partition 98GB Healthy Volume 1 D Backup NTFS Partition 20GB Healthy Volume 2 Recovery NTFS Partition 300MB Healthy Hidden Volume 3 FAT32 Partition 100MB Healthy Hidden Partition ### Type Size Offset Partition 1 Recovery 300MB 1024 KB Partition 2 System 100MB 301 MB Partition 3 Reserved 128MB 401 MB Partition 4 Primary 98GB 529 MB Partition 5 Primary 20Gb 99 GB I have tried the following Bootrec /fixmbr >Ok Bootrec /fixboot >OK Bootrec /RebuildBcd Total identified Windows installations: 1 [1] C:\Windows Add installation to boot list?

Did you by chance change any of the partitions as originally installed... by questions I ask because my default partition sequence is different. 1. Recovery 2. UEFI 3. Other-reserved 4. OS Data and if i change the sequence I can not boot... so had to boot to media, change the sequence back to default install. and all is well. when all goes belly up do a factory restore...
Hi Snuffy, I think there were some partition changes but these were ages ago, laptop was working fine after these changes and for a good period of time after. I would prefer not to do a factory restore if I can avoid it. Chris
