Clean install from a Lenovo installa. dvd: UEFI vs Legacy + Thinkpad setup acc. to Lenovo user Guide

2013-06-16, 13:18 PM

Machine: T520 bought Feb. 2012

O.S. W~7 Pro 64-bit

 

I want to wipe the harddrive, buy a Lenovo W~7 PRO installation DVD, and do a completely clean installation.

 

Lenovo User Guide (.pdf) Ch. 8, Adv'd Config, Installing Windows 7, p. 295 (212 of 298) says:

Start Thinkpad setup, then choose UEFI versus Legacy, then insert the installation DVD.

 

This obviously does not apply when the harddrive has already been wiped (necessary to 100% eliminate all traces of irreversible damage caused by a virus, including the re-installation partition (Q-drive).

 

When an intallation DVD is purchased from Lenovo, is not the first step to insert the DVD ?!! Then presumably there is an installation wizard resulting in a restored O.S. ?!!

 

If not, please tell me what surprises are in store, and where I can find a reliable written resource to consult !!!

 

Thank-you.

Re: Clean install from a Lenovo installa. dvd: UEFI vs Legacy + Thinkpad setup acc. to Lenovo user G

Hi, Z

Sorry, but I am not any further ahead in understanding any of the apparent contradictions, nor in knowing how to proceed.

 

Is it not the case here that the Lenovo User Guide is referring to just one of several possible types of clean install, and that it is totally ignoring the other methods ?!!

 

If my first step in re-installing Lenovo's version of W~7 Pro is to use a 3rd-party application to completely remove every file from the harddrive, how can I then perform any actions before inserting a Lenovo-supplied installation dvd ? I know that the BIOS software is separate from Windows, but is it still there ? Or, is the Lenovo User Guide referring to a situation wherein one does not first do a so-called "wiping of the harddrive" before initiating a clean reinstallation process ? Also, whether one wipes first or not, is the guide referring to a Microsoft (generic) installation dvd, and not referring to one purchased from Lenovo ? I should think that an installation dvd purchased from Lenovo would put back onto my computer exactly what was there before, and not ask me to make decisions like UEFI versus Legacy (in fact, the words "UEFI" and "Legacy" do not even appear in any computer profile file on my computer.

 

On the other hand, if the L~ User Guide's instructions do indeed apply to a wiped harddrive, the Guide says absolutely nothing about what criterion to use to make this "choice" between UEFI 64-bit and Legacy 64-bit.

 

(When the Lenovo's User guide's instructions raise more questions than original question, then those instructions are worse than no instructions at all !!!)

Hi,

 

By Start Thinkpad setup presumably the manual means go to BIOS and configure for UEFI.

 

Strange wording indeed.

You're over-thinking this and making it harder than it needs to be.  The manual isn't helping...

 

The BIOS is stored in non-volatile memory on the motherboard.  One would probably call it firmware, not software.  It is there regardless of what's on the HDD - or whether there's even an HDD installed.

 

Turn your machine off.  Turn it on again.  When you see the logo screen, hit F1 - multiple times if necessary.  That gets you into the motherboard's BIOS configuration utility - what the manual is calling "Setup".

 

Here's a snip below from the T520 BIOS configuration utility (actually from the on-line BIOS simulator).  In the StartUp tab you can see where UEFI/Legacy can be selected.  You can configure UEFI boot there.  Or "both".  Or - probably - just select Setup Defaults, save, and exit.

Hi, Z

Thanks alot for having taken the time to address this issue. I think "the problem she is solv-ed" (to quote Inspector Clouseau). I looked at my computer's Startup, and I have written down the settings for future reference. Just to make sure I understand: after wiping the harddrive, I turn on the computer/F1 to get to the Thinkpad Setup/Startup; I choose the UEFI/Legacy settings OR choose Default; then I insert the Lenovo installation dvd.

 

Again, many thanks. I hope that the rest of your day is pleasant one.
