IBM X60 is very legacy PC, very light and have active hard-drive protection so X60 is quite reliable. but due to its hard drive AHCI mode and no CD-ROM, it is really a nightmare when you plan to re-install the windows.
But fortunately, you can use the USB disk to install the Windows 7 very easily and fast (no driver problem in windows 7 for X60), so the key problem for install the Windows 7 on X60 become how to build a bootable Windows 7 installation media on USB disk and how to successfully boot it in the X60 when startup.
