After so many switch on/off
Pressing f8 while restarting it suddenly started to recover giving me errors such as mountable boot and others
It is working now but not properly
The following is the summary
My laptop Samsung Model NP350V5C-A0EUK
I had many problems since upgrading last August from Windows 8 - but it has been working fine since December (fixed itself)
However I updated 2 days ago with the following
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3156421)
Update for Windows 10 Version 1511 for x64-based Systems (KB3152599)
Windows Malicious Software Removal Tool for Windows 8, 8.1, 10 and Windows Server 2012, 2012 R2 x64 Edition - May 2016 (KB890830)
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3147458)
I updated and restarted fine. While working on Chrome it stopped responding. I restarted but it went into on off restart loop first. where no access to HD, KB or WiFi was possible and I had off screen.
After restarting several times
taking the batteries off and back on
the hard disc and wifi lights finally went on
The first error displayed unmountable-boot volume
that ws followed by several restarts untill suddenly wile talking to Samsung customer service ( who asked me to click on F4 then start it and keep my finger on it for endless tie)
suddenly it came back.. and startied to fix itself...I didn't get the 2nd error screen this time it was fixing something in the disc drive
it is working now .but it is not working well
for example I have critical error and restart each time I click on the windows start icon on the right bottom corner.
Now can I uninstall and restore to my previous state as it was working fine??
under update history there is uninstall latest preview build
not sure if window 10 has restore option as I can't find it.
The restore option in control panel displayes the following next the option (window 7)
