Windows will not start after SP2 Install

By psullivan201 ·
After installing the SP2 and clicking restart, all I get is a black screen with a message stating that Windows could not start because the following file is missing or corrupt: WINDOWS\inf\biosinfo.inf

I hit F8 but all options bring me back do the DOS screen with the "could not start" message.

I do not own a Windows set-up CD-Rom. Is my only option to obtain a recovery CD for my Sony computer? Is there any option besides a full recovery and losing everything on my hard drive (which, of course, I did not back up)? Any help would be appreciated.

Depending on the chipset, motherboard manufacturer, BIOS version, and CPU, installing Microsoft Windows XP Service Pack 2 can result in an unbootable computer system. The problem is generally associated with Intel "Prescott" CPUs and its chipsets, but not every such combination will cause a problem. As of this writing, motherboards exhibiting the behavior include:

Albatron PX865 PE Pro
Shuttle SB61G2
Jetway i875P
Soyo P4I865P
Aopen AX4SG Max
Asus P4P800-E deluxe
Abit IS7-V
Foxconn 865A01-G-6EKRS
Technically speaking, the problem revolves around the machine's BIOS not installing a production level microcode update. To check whether the BIOS is at the correct level, download the Intel Processor Frequency ID utility. The microcode version is identified by this utility as CPU Revision, which should equal at least 8.

Solution 1
If the Intel utility shows that you have the wrong microcode version, the primary solution to the problem is to update the system BIOS for your motherboard before you install SP2. Here are some motherboard manufacturer links:

The nature of the error message you got indicated to me that it was more of incompatibility issue between SP2 and software.
But first thing first, you have to make the Windows bootable.

1. Call SONY if there is any way to get around your problem.

2. Uninstall SP2. This requires booting Windows to Recovery Console. Read the Recovery procedure instructions carefully. If it allows that, you can uninstall SP2 and this is rather a simple process. If it does not allow, you need to borrow a XP CD. Using any OEM CD (I could be wrong, but Home or Pro may not matter) should be OK. Once the Windows boots normally, identify software you may need to upgrade, update, or patch to make it (them) compatible to SP2.

3. As a last resort, install a new HD, install Windows using the Recovery CD, and connect your current HD as a second HD to access all your data. Anything you had installed, you have to do it again, except SP2.

This, I meant to read Recovery procedure that came with your Recovery CD.

To dmiles? list of MBs that are not compatible to SP2, I?d like to add Foxconn 661M03-G-6EL. The BIOS date should be August 12, 2004.

you must update your bios from your motherboard producer. because the microcode revision on your bios is 5. Windows XP SP2 required microcode revision is 9
