Win7 can't get into system failure repair

Problem:

Because the computer shutdown is slow, and so impatient, forced to shut down, before all right, until last night to turn on the computer, prompting Windows error recovery, tried for a long time, prompted windows can not repair this computer, there seems to be no way. Later into the System Restore, finally saw a little hope, but prompted to open system protection to create a restore point, this is finished, the system is not going to go, how broken!!! On-line search, more reliable is the boot when the F8 into the safe mode, and then choose the most recent correct configuration (advanced) options, really vista, eager to restart Crazy press F8, but how can not enter the security mode, sad, this is to let me re-install the rhythm of the system? Then again a burst of wild search, why press F8 invalid, really all kinds of wonderful answers. One of the answers said that when the power is unplugged, and then restarted to enter the Safe mode, at the beginning of the answer is really not reliable, do not agree, until late at night 2 o'clock, or can not solve, forget, wash and sleep, tomorrow also work.

Come back tonight and start tinkering again, see that answer, thought or try it, this really put me happy blossom, unexpectedly successful, this time also give me a lesson, patience, do not force the computer do not do things.

Workaround:

Unplug the battery, connect the power, boot, in the start, unplug the power cable, restart, automatically jump out into the safe mode of the interface, choose the most recent correct configuration (advanced), into the familiar boot screen, start success.

For this problem spent seven or eight hours, solve the problem of obsessive-compulsive disorder Ah!!!
