I have upgraded from Windows 7 to Windows 8 pro on my computer. After installed the recent updates and made a reboot, Windows 8 get into an automatic repair loop and stuck in there. it displays the log file is located on C:\windows\system32\logfiles\srt\srttrail.txt and the repair is not working. Now I don’t have any windows 8/7 disc and can’t login to safe mode.
* Boot from your created recovery USB flash drive or system repair disc. Select your keyboard layout language.
* In the Startup Options Menu, click/tap on Troubleshoot > Advanced options > Command Prompt
* Type in the following commands one by one:
chkdsk /r c:
chkdsk /r d:
And then let repair go thowe again and that should fix the issues.
