    Error to load operating system.


    Hello,
    I am new here.
    I try installing windows 7 ultimate to my notebook Panasonic Cf-52.
    I initialised the bitlocker to my Drive C and also encrypted it, then I restarted the computer. At boot up, bitlocker requested to enter 48digits to confirm. I pressed esc to exit that screen and windows 7 started normally.
    The next day ,the second time I started win 7, I did enter 48digit and got successful confirmation.
    But the third time started win 7 , It is strange that the screen to request 48 digits was on again, this time I just pressed esc and continued to log on to windows.
    This morning , I started win 7 and I could not enter to windows.
    At nervous, I did insert the win 7 installation DVD and try the fix boot recovery. It works for some minutes and then request to restart. The problem is here, my laptop just only appeared the line "error to load operating system" when starting windows
    Now it just hang there. It seems that my SSD is locked by bitloacker.
    The Cf-52 has TPM v1.2, it uses the SSD intel Gen2.

    Any one can help me to load windows 7 normally?
    Can I use other computer to access the data on the SSD as the SSD contains the OS , not the data only?
    If I can not use the data on the SSD, Will I be able to just format the drive and install windows again ? How to do that ?
    I did try to install windows to the SSD but the win 7 installation wizard just not see the SSD as usual.
    Many thanks.

    I solved myself by using killdisk included in UBCD and gone all the data ! I reinstalled win 7 successfully.

    But i have another problem that happen many times. it is that after 2 days using and had win 7 updated. Win 7 got error reporting that it could not write to memory address ..... and it could not fix, I had to shutdown win 7. After shutdown and restart, win 7 just disappeared and my Cf-52 could not start to boot to win 7, it reported that no hard drive installed (i.e the boot agent could not see the SSD, how strange !).
    Anybody have such case like me ?
    Is it the Cf-52 hardware compatible with the Intel SSD or is it just the issue of win 7 and Intel SSD ?
