Ran my McAfee full system scan last night, selected the automated, "shut down system when scan complete" function, and went to bed.
This morning when I tried to log on, I get a black and white screen with the message:
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer. 2. Choose your language settings, and then click "Next".
3. Click "Repair your computer".
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Info: The windows Boot Configuration Data file does not contain a valid OS entry.
All that said, does anyone have any suggestions as to how I can save my laptop and recover?????
I'm not a tech person by nature, but live out of my laptop.
thanks for your knowledge and help!
I did this, only it won't read the disk, it starts to read it, you get two audible beeps and then it stops running the disk. Obviously since the dvd/cd drive is not functioning, you can't run the installation / recover disk. It also will not open in safemode.
I contacted Dell since it is a Dell XPS Windows 7, based system. Dell tech asked if I ran anti-virus software, I advise him that I ran McAfee. Dell tech stated the McAfee likely located a root virus, and aggressively deleted it, causign the boot error. Dell tech advised me to contact McAfee since it was their software that caused issue.
I contacted McAfee and the first tech said it sounded right, and that McAfee likely discovered serious virus and unfortunately changed boot configuration by deleting affected strings. When I asked how we fix this, the line went dead!
I redialed McAfee, got a different tech, who denied it could be McAfee and insisted I contact Microsoft so they could get me copy of the recovery disk. I repeatedly advised the tech that my disc drive was not functioning and that I already had the disk but it was useless since disc drive not functioning. This tech, told me he understood and gave me a reference number and phone# 877-568-2495....stating they would be able to fix the problem.
I dialed number, it was Microsoft CANADA!!!! Tech there told me it was a Dell issue and advised me to call Dell! All told, I've spent 5 hours, most of my day off, on the phone holding for next available tech, and been given the customary run around.

That is the sort of information that could be useful, but I need the exact laptop model number, year of manufacture, and maybe other information as well to find the correct online document that contains the product guide. If you can get access to another machine (and you must have done that in order to post) you might find it easier to seek out the docmentation yourself and track down the meaning of those 2 beeps.
There are plenty of posts about solving this problem, but they all seem to assume that you have access to a disk drive (CD-ROM or DVD) so that you can load repair or diagnosis utilities. If you really don't have a working disk drive then your laptop may need to go to a specialist repair shop or even back to the manufacturer ... but I'll keep looking for someone who reported the same symptoms as you have and found a way to overcome the no-disk difficulty.
At the moment we have to assume some drastic recovery action to remove a rootkit was responsible, but don't overlook the possibility that there may be other causes or we might miss something.
As an example of the meaning of beep codes, these are the codes listed for the XPS-400. Every XPS model may have a different set of codes, or they could be a standard set of Dell beep codes. This is taken from http://support.dell.com/support/edocs/systems/xps400/sm/adtshoot.htm
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
Reseating the memory modules may fix the beep code errors in the following table. If the problem persists, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
1-3-1 through 2-4-4
Memory not being properly identified or used
Memory failure above address 0FFFFh
If you hear one of the following beep codes, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
Microprocessor register failure
ROM BIOS checksum failure
Programmable interval timer
DMA initialization failure
DMA page register read/write failure
Slave DMA register failure
Master DMA register failure
Master interrupt mask register failure
Slave interrupt mask register failure
Interrupt vector loading failure
Keyboard Controller Test failure
NVRAM power loss
Video Memory Test failure
Screen initialization failure
Screen retrace failure
Search for video ROM failure
No time tick
Gate A20 failure
Unexpected interrupt in protected mode
Timer-chip counter 2 failure
Time-of-day clock stopped
Serial or parallel port test failure
Cache test failure
There should also be a set of lights on your laptop which can be used for error diagnosis (again, I don't guarantee that these light codes will be the same across all XPS models, but the ones I've looked at seem to use the same sequences for the errors listed) :
|CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.|
To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the front panel (see "Front View of the Computer"). When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.
The computer is in a normal "off" condition or a possible pre-BIOS failure has occurred.
The diagnostic lights are not lit after the system successfully boots to the operating system.
Plug the computer into a working electrical outlet. Also see "Power Lights."
A possible processor failure has occurred.
Reinstall the processor and restart the computer.
Memory modules are detected, but a memory failure has occurred.
|A possible graphics card failure has occurred.|
|A possible floppy drive or hard drive failure has occurred.||Reseat all power and data cables and restart the computer.|
|A possible USB failure has occurred.||Reinstall all USB devices, check cable connections, and then restart the computer.|
|No memory modules are detected.|
|Memory modules are detected, but a memory configuration or compatibility error exists.|
|A possible expansion card failure has occurred.|
|Another failure has occurred.|
The computer is in a normal operating condition after POST.
Thanks to Dell for making all this information available online (I couldn't find a way to request permisssion to reproduce it so I went ahead and did it anyway. It's an emergency).Message was edited by: Hayton on 14/03/12 21:36:55 GMT
