The installation of a Microsoft 64-bit Windows Operating System (OS) onto Lenovo Thinkpads with UEFI BIOS capability is very similar to a 32-bit install. The main difference is the BIOS configuration and HDD configuration prior to actual OS install.
After flashing BIOS, load BIOS defaults by pressing F1 at the Lenovo Thinkpad logo during POST, then pressing F9 to load BIOS defaults.
Navigate to Startup menu option of BIOS and Select Boot from left menu choice and select UEFI/Legacy Boot. Select UEFI only. Select UEFI/Legacy Boot Priority and ensure UEFI First is enabled.
Press F10 to save BIOS configuration and reboot the system.
Insert the Windows 64-bit Install DVD to begin the OS install. Note: Windows Vista 64-bit requires a DVD with Service Pack 1 slipstreamed. Press F12 to launch the Interactive Boot Menu and select the appropriate DVD drive to boot.
After the operating system has been installed and windows OOBE has completed, install the appropriate 64-bit Ethernet device driver.
The easiest method for the remainder of Lenovo Device Drivers is to install ThinkVantage System Update (TVSU). There is a minimum device driver version for use on Windows 7 systems installed via UEFI bios. TVSU will automatically install the correct versions. Minimum driver levels are:

The HDD being installed to must be in RAW, unformatted and unpartitioned status. The OS install with create a Boot Manager partition on the HDD prior to actual OS install. If during the initial Win 7 Install DVD do not boot and returns back to the Interactive Boot Menu, then there is existing partitions on the target HDD. To remove the existing partitions, the easiest method is to boot a Windows 7 PE boot disk and use the DISKPART utility to clean any existing partitions from the HDD. It will be necessary to boot in BIOS, then load Bios Defaults Via F9, then save and exit by F10. This will put system back into Legacy mode and allow for WinPE to address the HDD again. Run DISKPART to clean the drive. It is not necessary to create any partitions on the target HDD after using Diskpart to CLEAN the HDD. Then return to step 2 of these instructions and begin again.
Once OS install is complete , "Windows Boot Manager" will appear in Boot Priority Order.
