Windows 7 won't boot with HFS drive attached

I installed Windows 7 onto my 2011 Mac Mini. For some reason, when I try to boot Windows with my 2.5TB HFS+ external USB drive attached, I just get a black screen, I don't even see the Windows splash screen/logo.
If I remove said drive, Windows boots fine.
Also, if the drive is attached after Windows boots, when I click the Boot Camp icon and choose "Restart in Mac OS X" I get the error "Could not locate the Mac OS X boot volume". Again, if the drive is unplugged, I can use the Boot Camp icon to restart in OS X just fine.
Any idea what's going on?

maybe the 2.2TB issue afftects it, or the drive enclosure even.
And maybe if it was just 2.1TB it would work.
Even Lion had some surprises for customers with USB device drives.

Windows Won't Boot With USB Drives Attached

I just installed Windows 7 on my Mac mini but it won't boot into Windows automatically if there are USB drives attached. I have to hold down the option key at boot time and select the Windows partition manually for it to boot, unless I remove the USB drives first, then it will boot into Windows on its own. Does anyone know how to fix this annoying problem?

Sounds like your mini is set to boot order: boot from USB first.
On a PC you could go into BIOS and change boot order and enable/disable USB booting.
Not sure why or what is on the USB bus, type of drive and device that could also make a difference (and not be universal to the Mini)

IMac won't boot with external drives attached

I am using iMac 27" Late 2013 model upgraded to mavericks 10.9.4. Two external drives are always attached with it, one is segate 3.5" 2TB USB 3.0 drive and another one is 2.5" usb 2.0 drive.
when i start my imac with external drives attached it won't boot up. Stuck at plain white screen after a startup chime, not even any apple logo or any progress circle appears. And i have to detach all of my drives to make it boot.
This problem arises after upgrading to mavericks. Already tried resetting PRAM, SMC and checked Startup disk and verify disk with disk utility.

Raja,
Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Windows won't boot with Virtualization Techonology enabled

My Windows won't boot if I enable Virtualization Technology. I've read the other forums and have tried to both disable and update the Bluetooh and Wifi drivers before enabling virtualization again but that's not working. I've also updated the Bios but that doesn't work either.
Laptop: HP Envy TouchScreen 15-j052nr
OS: Windows 8.1 (64bit)
Bios: F.63 (I've tried F.65 A)

Hi @thyPot ,
I saw your post regarding the problem with the Virtualization. If you have already tried disabling and updating the drivers then give us call for further options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

Mac Pro won't boot if firewire drives attached

New Mac Pro (OS X 10.4.8) won't boot if my two daisy-chained LaCie hard drives are attached (firewire 800).
I can upnplug 'em and the computer cranks right up; can then plug the drive back in and everything's fine. Wazzup?
Thanks, Bob
Mac Pro 2.66 Mac OS X (10.4.8) User since Apple IIe

Similar problem with iMacG5 - if two firewire drives on bus wouldn't boot. Worked with one but erratic, also long delays opening files, finder erratic and hanging. Decided it was probably a chipset problem with the firewire bus. Since upgrading firewire enclosures problem gone away (I hope). How old are the drive enclosures. Oxford911 firewire bus has some problems with newer macs and OS. May get information on bus in "about this mac/moreinfo/firewire", or in disk utility window ("applications/utilities/disk Utility") WHEN computer is booted up with drives running.
OK, a Plug for Macpower's IceCube enclosures, bloody expensive but since I upgraded no problems. Also wiebetech.com have some cool stuff including internal SATA adaptors/cages etc.for older G5's and dual cores

Windows won't boot with my 3200+ at 2.2 ghz

Relative noobie here so here goes,
I just bought two sticks of corsair 500mhz pc4000 ram (256mb each) for my pc. I managed to get the ram to boot at 400 mhz but windows will not boot unless I set the system bus speed to 166. At 200 the bios will boot and it does detect the processor as a 3200+ with ram running at 400 mhz but right before the windows boot screen (the black one with the low res windows logo) I get a beep and the system restarts. Here is the info on my specs

So, the only product that's actually new is the nForce2 400 which looks like a low-cost version of the Ultra 400 chipset. Unlike its feature-rich brother, the nForce2 400 offers only a single DDR controller and will not be able to support the MCP-T south bridge. However, it will still offer full support for the new 400MHz FSB, DDR400, up to 3GB of memory and AGP8X support. Not bad at all, especially IF NVIDIA sells it significantly cheaper than the Ultra 400 chipset.

Not booting with external drive attached after itunes 10 installed.

Since installing itunes 10, my computer will NOT boot into Mac OS X with the external drive attached. It consistently freezes at a grey screen with the apple logo.
If the external drive is powered off, it will boot normally - but slowly. Anyone else with this glitch?

Try opening the Startup Disk panel of System Preferences and redeclaring the startup disk. You could see this behavior if your Mac isn't sure what device to use for booting.

W701 Won't boot with USB dongle attached

W701 with current BIOS (6KET46WW v1.12) will hang if there is a USB dongle for a Microsoft Explorer Mouse USB dongle in the upper left USB (2.0) socket on boot. Works fine if you put the USB dongle in the lower USB/eSata socket. Note that the upper socket on this 2541-W1Z is NOT a USB 3.0 port (silver, not blue). Course I don't want to put it in that socket since I like to use that for eSata... Apparently the same problem exists in the W5XX laptops as well, but I don't see a post discussing the issue on the W701.

Have you seen the thread

PC won't boot with CDRom Drives hooked up after iTunes install

Hello All,
After installing iTunes (initial, first time install on this machine) the computer would not fully boot. It would get to the Windows starting screen and the indicator bar would reach about 2/3 of the way complete and sit there. I tried rebooting in safe mode and it would still get stuck at seemingly the same point. After attempting several things to try and correct the issue, I finally stumbled upon that if I disconnect the CD drives the computer boots fine with iTunes installed. I've searched through the past records and saw some similar issues, but nothing quite the same and a lot of the fixes involved running diagnostics on the CD drives, but I can't do that currently as I have to have them disconnected to use the computer. Ideas? Help!
Thanks,
Jen

G5 won't boot with FW drives plugged in

I have been using a chain of five FW 400 & 800 drives for years. Today I went to lunch and came back to find my computer turned off. When I tried to turn it on, it clicks once, the little light above the power button lights for a fraction of a second, and then silence.
So I started unplugging things. My computer will boot just fine, if my chain of hard drives is unplugged from the back. They are attached on the FW 400 bus.
They are all self powered devices. Anyone have any thoughts?
Thanks,
Mark

Upgrading to SSD! But windows won't boot after copying drive.

I recently bought the great HP TM2t 2100 with all the bells and whistles along with an Intel x25m 120gb SSD (and Apricorn housing to use the old HDD as a backup drive.)
I followed all of the steps on the ez gig III software and copied the hard drive to the ssd without any errors. When I physically install the ssd (very easy!) and turn on the computer it says that Windows cannot be recovered. And will not boot windows. I did make Device Recovery discs but those are not able to be read either. Any suggestions on this? I have been trying to find an answer to no avail.
In the mean time I reinstalled the HDD and will try again after updrating all the drivers.

Well, I couldn't get the copied SSD to work, but as of right now I'm using the repair disks to restore windows to factory settings, the comp is only a weekend old and has no files of importance on it so I think this will be the best way. I will report my findings.

BootCamp won't boot with USB-drive connected

Hi everyone,
since I installed my BootCamp partition I encounter a strange problem. I have an LG external DVD-drive connected via USB to my iMac. Everytime I try to boot Windows while the LG is connected the boot process just stops and gives me a white display. If I unplug the drive from the USB-Port everything works fine, and once windows is booted I can even reconnect the USB-drive and it works fine. But as you might understand always unplugging and plugging really gets to my nerves. I know of a couple friends who encounter the exact same problem, they also complain about this...
Also strange is the fact, that if I boot OSX the LG is connected and everything works fine...
Searched the forum and web, and wasn't able to find something usefull...
I hope there is somebody here who can help me...
Thanks in advance...

MacBook won't boot with USB hub attached

My new MacBook stalls during the boot process when my powered, 4-port USB 2.0 hub is attached. If I unplug it from the USB port, OS X continues to successfully boot up.
Is this a known issue? The same hub works fine with my PowerBook G4.
Thanks.
MacBook 2GHz Intel Core 2 Duo | iPod 5G 60GB Mac OS X (10.4.8)

Yeah, I've already tried that. Much thanks for the reply, though.
It boots fine once the hub is unplugged. I'm just too lazy to remember to unplug the thing every time I start my MacBook. And, I'm generally annoyed because it all worked okay with my PowerBook G4.
So, anyone with a MacBook that boots up fine with a USB hub connected, what kind do you have? I need a recommendation.
Thanks.

Mac G4 won't boot with slave drive connected

I have two G4 boxes. 1-Dual 867 Leopard and 1 -Dual 1.25 Tiger.
I have been trying to clone the system drive of the Dual 867. Everytime I add the second drive to the 867 box and try to boot i get the "Flashing ?." I have tried various reformatted drives and the result is the same. I have even tried to accomplish this by using the 1.25 box. Same result.
if i unhook the 2nd drive (ie backup drive) both computers will boot as usual.
What is the problem?

Hi larbok, and a warm welcome to the forums!
I think it's the Jumper settings on the Hard drive.
Older G4s should be set to Master on the end cable & Slave for the Middle of the cable.
MDD usually use the Cable Select jumper settings on both drives.
Jumper settings are generally shown on the HDs themselves.

2nd HDD bay with HDD = notebook won't boot with HDD in 2nd HDD bay

I recently came into a Pavilion DV9308 Notebook. It was in decent shape, well looked new and since I like tinkering with laptops and the motherboard had the dreaded NVIDIA GPU failure going on, I sent the motherboard out to my motherboard dude and he put a newer NVIDIA video chip in, made some adjustments and modifications to the heatsink cooler etc. Along with my modifications including vent holes and sealing up the fan blowing assembly so when the fan turned on the hot air would leave the laptop it now runs Windows 7 64 bit with a 64GB Kingston OS SSHD and 4GB DDR2 800mhz ram. It runs like lightning and impresses people when they see it boot up in 15 seconds.
The problem is and the whole reason I picked this notebook to restore is because it has two acutal hard drive bays. Well ever since I've gotten the notebook It will not boot with a hard drive in both bays or a hard drive in Bay #2. I had to send the repaired motherboard back once because one of the ram slots wasn't working so this is happening on two different motherboards. I cannot find a reason why this is happening and have yet to find anyone that can help me with this. Can anyone explain to me what I'm doing wrong? I have all the correct drivers I think and the laptop runs at 130"F when pushed to the max! That is amazing compared to what it originally ran. It would be awesome if someone could please help me with this. Thanks.

Hello jason9922. I understand your notebook won't boot with a hard drive in the second bay.
When you say that the notebook won't boot with a drive in the second bay what exactly do you mean? Does the CAPS LOCK key flash or do you get an error?
When you have the hard drive installed can you access the BIOS? If so, is the hard drive detected within the BIOS?
I'll keep an eye out for your response. Have a great day!
