No OS Installed

[Jahbriel]

Sorry to bother you again. My laptop has Windows Vista but it does not boot until the end. I got 0XC000000F a mistake (which I mentioned in another post) and recently, I have resurfaced an attempt to repair the installation of Vista, but it can not be fixed, with a problem -

>> Startup Repair fails and reports the following problem signature:
>> Event Name: StartupRepair V2
>> Signature 01: ExternaMedia
>> Signature 02: 6.0.6000.16386.0.0.0.0
>> Signature 03: 0
>> Signature 04: 65537
>> Signature 05: unknown
>> Signature 06: NoOsinstalled
>> Signature 07: 0
>> Signature 08: 1
>> Signature 09: FixPartitionTable
>> Signature 10: 1168
>> OS Version: 6.0.6000.2.0.0.256.1
>> Local ID: 1033

I am feared by this line the most: >> Signature 06: NoOsinstalled
What is it? Is it repairable?
Thanks

I think that you are using any AV program which might be loading in real mode or any BIOS based antivirus which is enabled when you are trying to correct this issue perhaps?

I have checked that there is no AV program installed & the MBR protection in the BIOS is not enabled. Thanks for the comments, any other ideas?

I think there is not enough Hard drive space for the install of the operating system to complete so it might be closing down prematurely before it completes the install.
