Installing Windows 7 64 bit on ThinkPads with UEFI BIOS

<p>The following instructions may be helpful to customers who wish to install Windows 7, 64 bit versions on ThinkPad systems with UEFI enabled BIOS. &nbsp;Note that 32 bit versions of Windows do not support the UEFI features, so only 64 bit versions can be enabled by 64bit UEFI firmware.</p> <p>&nbsp;</p> <p>The installation of a Microsoft 64 bit Windows Operating System 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. &nbsp;&nbsp;</p> <p>&nbsp;</p> <p>1)Always obtain the latest BIOS version for the Thinkpad system being installed from the link below. <strong><a href="http://support.lenovo.com/en_US/detail.page?LegacyDocID=TPAD-MATRIX" target="_blank">http://support.lenovo.com/en_US/detail.page?LegacyDocID=TPAD-MATRIX</a></strong></p> <p>&nbsp;</p> <p>2) After flashing bios, load bios defaults by pressing F1 at the Lenovo Thinkpad logo during POST, then pressing F9 to load bios defaults.</p> <p>&nbsp;</p> <p>3) &nbsp;Navigate to Startup menu option of Bios and Select Boot from left menu choice and select UEFI/Legacy Boot. &nbsp;Select UEFI only. Select UEFI/Legacy Boot Priority and ensure UEFI First is enabled.</p> <p>&nbsp;</p> <p>4) Press F10 to save BIOS configuration and reboot the system.&nbsp;</p> <p>&nbsp;</p> <p>5) Insert the Windows 64 bit Install DVD to begin the OS install. &nbsp;Note: Windows Vista 64 bit requires a DVD with Service Pack 1 slipstreamed. &nbsp;Press F12 to launch the Interactive Boot Menu and select the appropriate DVD drive to boot.&nbsp;</p> <p>&nbsp;</p> <p>6) After the operating system has been installed and windows OOBE has completed, install the appropriate 64 bit Ethernet device driver.&nbsp;</p> <p>&nbsp;</p> <p>7) The easiest method for the remainder of Lenovo Device Drivers is to install ThinkVantage System Update. &nbsp;There is a minimum device driver version for use on Windows 7 systems installed via UEFI bios. TVSU will automatically install the correct versions. &nbsp;</p> <p>&nbsp;</p> <p>Minimum driver levels are:</p> <p>&nbsp;</p> <p><img src="http://forum.lenovo.com/t5/image/serverpage/image-id/4559i6075C873769884A4/image-size/original?v=mpbl-1&amp;px=-1" border="0" alt="Min drivers for UEFI support.jpg" title="Min drivers for UEFI support.jpg" align="center" /><br /><br />TVSU is available at: <strong><a href="http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&amp;LegacyDocID=MIGR-61432#update" target="_blank">http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&amp;LegacyDocID=MIGR-61432#update</a></strong></p>

<p>Mark - now with Windows 8 and it's favoring of UEFI - are there any instructions you can provide for successfully installing Windows 8 while changing a machine from Legacy/UEFI to only UEFI?  I know the disk must be GPT, change, BIOS settings, and install Windows 8 - but how do you attack this problem?  Thanks</p>
