OptiPlex 755 with a 240GB SSD and Windows 7
Posted on 2013-01-16
I'm having a problem with a OptiPlex 755 that recently was upgraded with a SSD 240GB, trying to install Windows 7 64bits.
I know that Windows 7 is not officially supported, but, here is my thing.... I did try installing Windows 7 x32, Windows Vista 64, and Windows XP SP2 and the results are the same. In the first Windows screen the installation stops.
I even try with a SATA Barracuda 150GB and I cannot install the OS in that driver neither.
The logic explanation is that something is wrong with the hardware, however, if I connect the original SATA 250GB HDD with Windows Vista 64, the machine boots correctly.
I was able to start the Windows 7 64 installation in safe mode, and the installation halt (blue screen) when is loading a driver called disk.sys....
Any ideas that could help to install Windows 7x64 in that computer?
