I down loaded your latest version of Ultradefrag 4.3.0 today to my HP ze4560us
laptop computer running Windows XP service pack3. I was interested in the
defragging capability during boot time. Well I enabled the boot time
defragmenting option and restarted the computer.
Well it won't boot up!! I get to the first brief screen that says "Press esc
to change boot order, press F2 to enter set-up, F12 to boot from Lan. After
that I simply get a blank screen with just a blinking underline mark _ No keys
work nothing. Use power button to shut down and start up again. Same result as
above. Tried multiple times. Tried all the F buttons. But no keys work. I have
all the Recovery disks. Do I have to use one of them to get it to boot up?
What do I do? Tell me I did not just lose everything. Please help!!!
No there is no need to reinstall the system.
You need to boot into safe mode, which is done by pressing F8 before the
Windows logo is displayed and after the BIOS lists the found hardware or the
computer manufacturer logo vanishes.
You can the run UD and disable boot time scanning or run the command boot-
Now reboot and check the boot time defragmenting script, please quote it in a
Thanks for a reply. I am not even at the point to where the Windows logo
appears or the BIOS finding hardware. There is no hard drive activity. No keys
work. It seems as if it is not even recognizing that the hard drive is even in
I did though put in a HP QuickRestore System Recovery CD disc 1 of 5 that I
had. When I did that it I got to the first screen of the Quick Restore and
simply exited out. When I do that it gets me to this C:> I take it this is
the command prompt. Can I get to Safe mode from here. The keys on the keyboard
To get into safe mode do the following:
1) restart your system
2) while the HP logo is displayed tab the F8 key many times repeatedly
3) you should get a screen like one of those displayed at Getting into
Windows Safe Mode.
4) follow the on-screen instructions to select Safe Mode
UD is not executed if booting into safe mode, so you will get a minimal
Windows desktop, where you can disable boot time defrag.
!!! As said before do not use the recovery disks, since you will loose all
your personal data !!!
Could you take a picture of the current screen and add it to a post of the
Sorry, it is the Support
Rereading your initial post shows, that you are not even getting to the point
where Windows starts.
The cause of this problem must be something different, since UD does not
change anything that could cause this, if you enable boot time defrag.
What else did you do before installing UD, enabling boot time scan and
rebooting your system?
After downloading UD I ran the defrag for about 15 minutes just to see how it
went. Stopped it after 15 minutes. Then enabled the boot time scan and
rebooted. Thats it. Yes I am not even getting to the point of Windows
I let someone in the IT/helpdesk area at work take a look at the hard drive
who is a whole lot more knowledgable than I with computers. I will try to
summarize what they said.
They said the Bios is not even recognizing the drive. They used an XP boot CD,
ran hard drive test, and mentioned something about a partion program. Not sure
of the exact process they used to check out the drive but the main thing they
translated to me was during their process they got an error code/message of
"unmountable boot volume". The computer can't boot because the file system in
the boot area is messed/corrupted/ missing.
Does your restore disk set include a regular system disk?
Since it is a HP system, it will usually consist of a Restore Plus CD and
an Operating System CD, if this is not the case you may want to get a
regular Windows XP installation disk from your IT.
You will have to boot from the XP operating system or installation disk, not
the restore plus disk and follow the instructions at Description of the
Windows XP Recovery Console for advanced
users under the topic Option 2
for starting the recovery console.
I would first try the FIXBOOT command and restart with the CD removed.
If this does not help try the FIXMBR command, if there is still no joy,
you will have your IT to rescue your private data from the disk and use the
recovery disks to get your system back.
Finally, UD is not messing around with the boot sector, nor with the master
boot record, so there must have been something else, which surfaced in making
your system stale at boot.
Have used Ultradefrag on 2 different laptops wiht similar issues. Turn off the
boot time scan and the computer screen goes blank after the bios screen
appears. No message, nothing happens.
Note that it worked fine until I turned the bbot time scan off.
Have it on another laptop and am leaving it on for now so I don't have the
same issue crop up.
Once I managed to get into windows, I tried turning it off again- no change.
Uninstalled ultradefrag. Now there's about a 1 minutye delay and the computer
You can claim its not the boot scan, but the same thing happening the same way
on 2 different computers says different.
Wher is the script stored and which file calls the script. I can use a Linux
live CD to access the necesarry file and make the changes. I just need to know
which ones and what directories they're in.
Check out the FAQ and
read the section Miscellaneous => How can I disable the boot time
Are you running any drive encryption or imaging program on both systems?
Hi I am using win8 pro on laptop and got similar results regarding boot time defrag but not only UltraDefrag (5.12 and beta 2). It is with almost all defrag on the planet: perfectdisk, diskeeper, smart defrag, puran...
some of them I got BSOD right after windows logo screen when enable boot time defrag. For UltraDefrag and Diskeeper, while they perform boot time defrag successfully, if I turn off boot time defrag, next boot I got stop at that windows logo screen with hard drive light off, have to press on/off button for 5 secs switch off my laptop. But next boot everything ok. But if I shut down the laptop normally, next boot it stop at that windows logo screen again. It starts up and enters windows successfully only after I hard reset. Now I simply did not install any defragger. Yes I know UltraDefrag does not offically support win8 but, any idea?
Windows Bitlocker is disable and no drive encryption software running. Only Windows built-in shadow vol copy service and system restore enable.
Sorry for the inconvenience.
Users have reported that they have no problem running the GUI or the console interfaces, but there was no mention if the boot time interface was run successfully.
I seem to have to reinstall my whole system to get a test environment for Windows 8, but that will need some time.
Meanwhile I would recommend to not use the boot time interface until we have fully tested Windows 8 support.
Thanks for you reply Stefan. I searched the net and found out some people got the same booting problem after install certain windows updates. This maybe the case since this only happen after windows update this month. But strange only with defragger for my case
May be there is another set of boot files, that are not currently skipped, so we will have to investigate further.
Today, I installed and then enabled the boot time scan and rebooted. The system will not boot. Windows 2000, and a mirrored SCSI drive.
Could you enable the creation of the debug log and attach that to a new bug report.
