HP ProDesk 490 G1 MT does not boot when external "WD - My Book - 4 TB - USB 3.0" is connected

I'm troubleshooting an HP ProDesk 490 G1 MT.
Intel Core i7 - 4770 CPU @ 3.40 GHz GHz
16.0 GB RAM
Windows 7 Professional Service Pack 1 - 64 bit
HDD 1 GB
HP doe's not boot if any external hard disk drive is connected. All dimensions and all brands, USB 2.0 or USB 3.0
PC don't boot even if I command from BIOS to boot via internal hard drive.
It try, I see Windows is loading, but then i see the PC is searcing a boot system, a MAC address and then it is lost and alone until I disconnect the external hard-drive ...

The fact is that I have four Acer (2 desktop, 1 nettop, 1 Netbook) and 1Notebook HP (2006/2007) that not have this issue.
When I connected the first time this morning the external hd, my mouse Logitech M570, trackball - wireless, went crazy. I searched and found a solution on Logitech Website.
More:
I wrote:
... " ... All dimensions and all brands, USB 2.0 or USB 3.0 ... " ...
But is too long on Verbatim, Toshiba, WD, Samsung, Freecom, Lacie, sites.
But "Never say never again", I tried and the site WD is unavailable.
On the other hand is a common issue on HPs, I can see on this site.
I'll try the solution at:
http://h30434.www3.hp.com/t5/Desktop-Lockups-Freezes-Hangs/Pc-hangs-at-hp-boot-screen-with-external-...
of "jako 1x4". It didn't work for "MrWoogy", but I have a USB 3.0 hd.
Tank you for your doctrine and wise advise.

HP Z620 does not boot when external Seagate hard drive is connected

I'm troubleshooting an HP Z620 workstation with 32GB RAM, one 500GB HDD + one 1TB HDD running Win 7 Enterprise 64 bits, this user has 2 external USB 3.0 HDDs, one Buffalo 2TB + one Seagate Desktop Backup Plus 4TB; the problem comes when the external Seagate HDD is connected and the PC is turned one, for some reason the PC does not boots, it shows a message that states "Non-disk or no boot disk error" and sometimes it tries to boot, but then goes thru the "Windows repair option" or "Start Windows normally" routine, none of these results on starting the PC.
The only way this PC starts and works properly is when PC is started with the external Seagate HDD disconnected and then connected once the Win 7 is up and running; the problem described above does not happens with the external Buffalo 2TB HDD and the Seagate HDD have been tested throughly and no errors or problems have been detected on it.
I'll really appreciate your attention to this, as well as your prompt response.

Hi:
You may also want to post your question on the HP Business Support Forum -- z Workstations section where there may be more folks familiar with that issue.

KT6V + sempron 2800 does not boot when BIOS saved

Hi,
I have just bought a new sempron 2800 to be use on a KT6V LSR. I plugget in my KT6V but was not recognised well (but all was working ok with windows). To be recognised, I have flashed with the last bios of MSI my motherboard... and now I have the following problem:
- I clear CMOS, then boot. It comes ok (processor detected and set a 1200Mhz)
- Then CMOS has a bad checksum: I enter setup, then load default, save.
- I reboot: the computer does not boot up.
If I re-clear CMOS I can re-enter setup and modify frequencies or other options. But when I save my modifications, then the computer does not reboot anymore (I have to re-clear cmos again)...
I tried to apply the configuation I found in this thread:
http://forums.amd.com/lofiversion/index.php/t69536.html
It says that SDRAM must be at 333, FSB at 166 and multiplicator at 12. When applying this settings, it does not boot (the leds indicate that the chipset initialisation (the first step) does not pass).
If I just load biios default, the leds indicates that it fails when checking the memory (second step of boot). I suspect that it's a problem of memory (but my memory was working well before !): it's 2x512 of DDR 400.
Any suggestion is appreciated :D . I spent several hours trying to configure the bios but it does not boot..
(I'll also try to find help on AMD forums...)
(Some extra info: my PSU is 26A for 12V, so it seems that it's not due to the PSU (as I read in the FAQ of this forum).
Thanks,
Ptitmain.

System does not boot when PCIe express Card is inserted in system. Using Spartan-6 PCIe Integrated Endpoint Block 1.3

Hi,
I am using Spartan-6 PCIe Endpoint Block core v1.3 and I am using ISE 12.1. I have used the PIO example design,
modified it according to our design.
The core is configured as below:
BAR0 - 8KB, 32-bit, Memory Type
Lanes - x1
Clock - 125 MHz (system clock)
The card is a custom board. When the card is pluged into the system the system does not boots, it hangs.
I have tried debugging using chipscope and monitored trn_lnk_up_n, trn_reset_n and trn_clk. trn_lnk_up_n stays
high (deasserted), trn_reset_n stays low (asserted), trn_clk is low (No clk).
What might be the issue?
Thanks & Regards.

Thanks Gabor, for the response.
I refered couple of answer records like AR# 34873 and AR# 34894, I monitored trn_reset_n, sys_reset_n, clock_locked, PLLLKDET and RESETDONE signals as suggested in AR# 34894.
Status as follows:
SYS_RESET_N = 1 (deasserted)
TRN_RESET_N = 0 (asserted)
CLOCK_LOCKED = 0 (deasserted)
PLLLKDET = 0 (deasserted)
RESETDONE = 0 (deasserted)
which means the transceiver PLL frequency is not within the predetermined tolerance. Is this problem related to the PCIe Jitter Attenuator I am using on the board to derive 125MHz from 100MHz system Clock.
Thanks & Regards

Windows Server 2008 R2 Does not boot When Back up drive removed

I have a windows Server 2008 R2 Standard server RAID 10 installed. I have a non raid drive installed as the backup HD. The Backup drive is now failing. When I went to switch it with a new one the system does not boot and is asking for
a boot drive. I have been searching for solutions and cannot find any. Any ideas?

Hi,
Could you confirm if your boot volume is on that non-RAID disk (maybe 2 volumes on that disk and one of them is the boot volume)?
At current situation, first please test to connect the failed disk back to the device and see if it will help.
Or you may need to run a boot-up repair with an installation disk.
If you have any feedback on our support, please send to [email protected]

Computer does not boot when pxi 1033 is connected

hiiiiii...........i am using NI pxi-1033 for my application & this pxi is connected to my system through PCIe-8361. i am using it from last 10 months, now suddenly my computer does not boot up. i start pxi first then start the computer but computer screen shows no signal. there is no blue screen error.
can you give me any point to troubleshoot the problem.

This probably doesn't help, since your setup used to work, but I have had to run the MXI Compatibility Tool on more than one PC.

One PC would only boot one time in ten, before running the tool.

2012 mac mini does not boot when usb 3 drive is connected

I have a late 2012 Mac Mini, Ivy Bridge, that has a USB 3.0 external hard drive connected to it. If the hard drive is powered on when I power up the Mac Mini, I get a light grey screen, but never see the Apple logo and the system just sists there. If I boot the Mac Mini with the USB 3.0 drive connected, but powered off, the Mac Mini boots just fine. Interestingly enough, if I reboot the Mac Mini with the USB 3.0 hard drive attached, the Mac Mini boots normally. I have installed all of the OS patches I can find and have not had any luck in resolving this. Does anyone have an idea what might be going on?

Something to check. Power everything down. Turn on
your external drives then do a PRAM zap booting the MIni.
http://support.apple.com/kb/PH11243
It may or may not help.
If it doesn't, then check the system log starting from the time
you start up the Mini and see what the last entry was. Wait a fair
amount of time so a gap in time in the log can be seen when you turn
the drive off. Could determine if it is some hardware issue, as BDAqua
was suggesting, or a driver issue.

OS X Lion does not boot when my Time Machine disk is connected

Everytime I boot or reboot my MacBook Pro I am stuck at the grey screen and OS X Lion will not boot. When I disconnect my Time Machine disk (external disk connected via usb) I suddenly get the loading screen and OS X Lion boots properly.
Pretty anoying I think, does anyone have a solution for this problem?

Have a look at the boot log messages, using Console.app (also with the "dmesg" command), and see if there's a clue there, or, set the boot process logging to "verbose" (i.e., using TinkerTool System) and find out what's really going on live at boot time. (Also, do you have BootCamp setup, or any ofther bootable partitions?)
Hope this helps.

Windows 8 and Canvio Desk 3TB: System will not boot when external hdd is connected

http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-e-g/HP-PAVILION-A6109N-amp-windows-8-System-w...
Hi,
just recently upgraded to Win Pro on my HP PAVILION A6109N. I also bought a toshiba canvio desk 3TB. What I notice is that if I reboot my pc with the extermnal HDD connected, my system will not boot.
I have check my BIOS boot settings and the order of the boot.
I have tried disabling USB Legacy Support in the BIOS
I have reformatted the external HDD
but still my desktop will not boot if the external HDD is connected....If I disconnect the external HDD...the system will boot up ....
I am at a loss....*** scratching my head ***

Update: The only solution for me was to format the drive as ext3 and plug it into one of my Asus RT-N66U USB ports, as most routers don’t yet recognize 3TB drives as NTFS. It’s not much help to people who don’t have a router with this capability, and it also slows transfer rates to ~12MB/s.
Given the short length of the cable, your only other options are to have the 3TB Canvio sitting right next to you so you can unplug from a front USB port before each boot, or place it towards the rear of your desk and crawl under the desk to disconnect it from your PC prior to each boot.
It's a pity because Toshiba produce great internal HDD's, but my experience when it comes to external drives is they're simply junk. I wish I had read the reviews before purchasing.

MacBook Pro does not boot when 'cold', Windows 7 on the other hand boots without any problem

Hey everyone,
I have a strange problem with my MacBook Pro mid 2009 13" running OSX Mavericks. For more than a year I have trouble booting my laptop. A 'cold' start (a fresh boot) usually ends with the prohibition sign on a grey back ground (starting in verbose mode results in the error message that the main drive could not be found). So far so strange.
I have Windnows 7 installed as a bootcamp partition. If I start the laptop with Windows booting is no problem and Windows runs smoothly (what a terrible world we live in). If I let the laptop run for let say 10 minutes and restart the laptop Mac OS starts without any problems. (It doesn't work if I immediately restart after windows booted; also reinstalling Mac OS as a clean install from an external medium did not change the problem; disk utility always finds something to repair but neither discpermission repair nor disk repair got rid of the problem).
As an additional comment a WD 500GB Scorbio Blue replaced the original hard drive about a years ago. I had no problems with the hard drive initally and I can't really believe that there is a problem with the hardware, I mean, why does Windows start and Mac OS doesn't?
Thanks for your time and help!
Marco

This isn't a direct answer to your issue but have you considered installing Wine so you can run the occasional windows app directly in OSX? It's a much more elegant solution IMHO. This avoids restarting all the time with Bootcamp and avoids crashing all the time (and the security risks) with Windows running.

Macbook pro does not boot after upgrading ram

I have a macbook pro late 2011 which runs with mavericks operating system . I have tried to upgrade my macbook to 8Gb. Macbook does not boot when the two ram slots are filled with 4GB ram but runs well when the slots are filled with 2GB ram. When i try them individually with one slot of 2GB ram and another slot with 4GB they run perfectly which shows status ok in the RAM info. What could be the problem .

Around here, most of us recommend only Crucial and OWC for RAM because it's guaranteed to work with Macs and it's what most of us have. If I were you, I would return the RAM and look at purchasing RAM from either Crucial or OWC. If you can't get their RAM to work then you'll know that there's some trouble with your actual slots.
Good luck,
Clinton

[SOLVED] ArchLinux does not boot if AC adapter is plugged in.

Well, actually it does not boot when AC adapter is unplugged too! When I boot ArchLinux it stops working (i.e. the screen becomes completely black without the chance to recover it) just after it says: "Waiting for UDev uevents to be processed".
The only workaround I found is to plug in the AC adapter before turning the computer on and unplug it exactly after it started booting the kernel. Otherwise it does not complete the boot process (as I said, it stops at: "Waiting for UDev uevents to be processed").
More, on KDE startup I always see a message concerning Power Management, but it is too fast and I cannot read it. If I go to System Settings > Power Management I see this notice: "Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it inside `Startup and Shutdown`". Do I have to add `powerdevil` to `Startup and Shutdown` as pre-kde startup service?
As for my configuration I have this modules in my rc.conf:
MODULES=(ac battery button acpi-cpufreq cpufreq_ondemand acpi)
The last one was acpid, but at startup it said it could not find that module, so I changed it to acpi.
Thank you,
rubik

Ok, I tried and I got something
+ -------------------------- MODULES -----------------------------------+ Result +
| ac battery button acpi-cpufreq cpufreq_ondemand acpi | FAIL |
| battery button acpi-cpufreq cpufreq_ondemand acpi | SUCCEED |
| ac button acpi-cpufreq cpufreq_ondemand acpi | SUCCEED |
| battery | SUCCEED |
| ac | SUCCEED |
| ac battery | FAIL |
+--------------------------------------------------------------------------------+-------------------+
As you can see, it fails booting only when ac and battery are loaded together.
EDIT: With lsmod I can see nobody uses either ac or battery, so can I remove them from MODULES? This would solve the problem.
Mod Edit: I added code tags -- that output was just too ugly I took them back out, they did not help

Tecra A11-11N does not boot after CPU upgrade

Hi,
I would like to do a processor upgrade for my Tecra A11 11N from the i5-430M to a probably much faster i5.I thought the i5-580M would do, but the laptop did not boot when i installed this processor.
I reverted back to the 430M, did some research on the internet and found out that the 580M has a very high FSB speed and that is what probably made it not to work/incompatible with my machine.
http://ark.intel.com/products/43537/
http://ark.intel.com/products/49653
http://ark.intel.com/products/49652
and also at http://ark.intel.com/
Now i went back to the computer shop,returned the 580M and got an i5-560M as i compared it's specs and saw it would be compatible as it has the same FSB speed with the 430M.
I then later on in the day tried to install this cpu as an upgrade BUT alas!
It STILL WON'T BOOT ALSO.
I was left dumfounded.Processors in the same familly line are supposed to be compatible with one another provided:Lithography, FSB and socket type are similar.
Or what am i missing here?
I have done processor upgrades in many instances for both desktops and laptops and this is the first one that has left me with no words to say!
please offer some help/advice.

I solved this processor upgrade problem on my own.
I did some little research on what limits processor upgradability on computers and i
found out that BIOS was one of the factors that play a key part.
So,i went on a mission
to see if i could upgrade my BIOS and whether it would solve my problem.
I found this link to be very informative:
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=66624
I then downloaded the latest BIOS version for my laptop from this link:
http://uk.computers.toshiba-europe.com/innovation/download_bios.jsp
The following link gave me proof that the BIOS update would not bring any problems to my
machine and that there is already someone who had done it and not encountered any problems.
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=62459
Just to make sure that you are on the safe side,before carrying out the procedure to update
your BIOS,make sure you have a fully charged battery in addition to the AC plugged in.A power
outtage during this procedure would instantly kill your machine.
The BIOS installation took less than 3 mins.I copied the executable on the desktop and run it
from there.
On rebooting,the new BIOS was installed.The new BIOS version was 3.40 dated on 05/18/2012 while
the older one was version 2.0 dated on 04/03/2010.
From Intel's website,the i5-430M was released on Q1 2010 while the i5-560M and i5-580M were
released on Q3 2010.
It is pretty obvious that by the time BIOS version 2.0 was release,these two newer processors
had not been released and that explains why they were not being recognized when i installed them.
I finally swapped the 430M with the 560M,assembled back the machine and powered it.
Voil!,the machine booted to it's new life.Everything is as was before!
So far i have not seen any problems even to do with overheating or the cooling fan spinning any
faster that before.It is all the same as before.There is considerable performance gain with the
uprade.I am a software developer and my various development enviroments including compilers,
debuggers,database and deployment servers have all been running way way faster than they were!
I believe the 580M can also work but unfortunately i had returned it back to the shop.
There is no reason for buying new machines when we can upgrade the ones we have.What will
happen to the older ones?This means more electronic waste and so does new machines.Let us try
to make better use of the ones we have a in turn,SAVE OUR ONLY PLANET EARTH FROM GLOBAL WARMING!

New MBP i5 does not boot after hard disk swap

Hi there,
I received my new i5 MBP today. After booting it once with the installed HDD to check if it's ok, I exchanged the hard disk for the one in my Late 2008 Macbook Pro. After doing this, my Late 2008 Macbook Pro boots fine with the (new) hard disk from the new i5 MBP, but the i5 MBP does not boot with my old hard disk.
To give you some details:
- I have installed 10.6.3 on the (old) hard disk that's not booting.
- The i5 MBP boots fine from the installation DVD
- Disk utility finds and can read my hard disk, no errors
- PRAM NVRAM reset did not help
- when booting in safe mode, I can see the system stop booting after or while loading Extensions.mkext
My guess is, it tries to boot and load the wrong Extensions for the new system (CPU? GPU?). I have no idea how to fix this.
Any help would be greatly appreciated!

Focx,
Welcome to Apple Discussions.
Inserting the drive from an earlier model MBP will probably not work. The version of the system you have on that HD is designed for earlier hardware so when you put in in your new machine it's going to be recognized. What I'd recommend is re-installing the disk that came with the new machine and of course putting the 2008's disk back in the old machine. Then use Migration Assistant on the new machine and migrate your data from the old machine into the new machine.
This will provide a much more stable system and should work just fine.
Regards,
Roger
