Bootcamp boots in parallels but not form start up.

hi i was having problems installing bootcamp and installed it to my partitioned (partitioned by bootcamp installation app) side of the HDD it will load up perfectly within Parallels but not through the boot selection on start up and shows a error about no bootable something.
should i uninstall the bootcamp and parallels and try to install it again through the utility or how do i set it to be able to boot form start up to it withought a Virtual machine?

1. Remove the Parallels VM.
2. Remove the Bootcamp Partition using Bootcamp Assistant.
3. Create the Bootcamp partition again using Bootcamp Assistant only, build a USB as directed and if necessary.
4. Bootcamp Assistant will automatically boot to the Windows Installer and start it.
5. Install Windows as directed by the Installer.
What kind of problems were you having during the initial installation that made you switch to Parallels-based installation?

X41 (1866-ED5) Will charge battery but not run from it.

I haven't used this laptop for about 5 weeks.
I plugged it in it started charging from 27% up to 80% like normal.
Then it was slow to charge the next few percent. It got to about 83%
Then I unplugged it for a bit to move it. It ran off the battery at this point. I plugged it in again and it went up to 93% at a normal rate and stopped.
I went to move it again about an hour later and unplugged it and it lost power.
Now it will show the battery in windows but it will only start up and run if it has AC.
The battery report shows it's fine. The battery is not very old and only shows 39 cycles.
What should I try?

sounds like a bad battery. you could try running a cycle on it. let it discharge completely and then charge it up. see if there's any change. being that it didn't charge to 100% and it took a long time to get to 83% sounds like there's a problem with the battery.

I can boot into Arch, but not DM or DE [solved]

I just recently installed Arch in VirtualBox. Arch is running on 1GB of RAM (changed from 512MB) and 8GB of storage with dynamic size enabled. I set the specs low as I want this to be portable and load on almost any machine. When it boots up I can access command line, but not DM or DE. If I set it to automatically boot into a DM or DE, it hangs (black screen). I have tried different DMs (GDM, KDM, SDDM) and DEs (Gnome, KDE, Plasma), but I get the same problem. During the boot process I get intel_rapl: no valid rapl domains in package 0 and SMBus base address uninitialized. While researching though, these problems don't appear to be linked to mine. Any advice would be helpful, thanks.

Why did you chmod it? This is not in the instructions.

XDM is also not part of the instructions for testing TWM. If you start doing random other steps, we will not be able to help you as we will not understand what state your machine is in.

Please post the *full* output. The server terminated successfully suggests a problem with your xinitrc, so as ewaller requested, we'll need to see that - after you provided the actual output and error messages you are getting.

Can boot in windows but not imac

I can start my imac by pressing down the option button on startup, but I can only get on windows partition. When I try to start up in mac, I get the grey screen with the apple logo. I have tried everything. Is there a way to fix the problem with the start up/boot up on the windows side?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 4
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

XP boots in Fusion but not Bootcamp

I'm new to the Mac, had my 24" IMac for nearly a week now. Successfully been running XP SP2 on my bootcamp NTFS partition, and also run the same partition with Fusion.
All was well until today, when I decided to turn on automatic updates within XP (whilst in Bootcamp). Some 92 updates later, the machine rebooted, but the screen just went grey and refused to boot. So I eventually had to power off.
The situation now is that if I hold down the option key, I get my list of drives (OK). I then click on the Windows partition and the mouse just freezes (not OK). If I wait long enough (about 5 minutes), the boot loader gives up and just boots into OS-X.
But strangely, I can still run Fusion and run the Bootcamp partition just fine.
I then shut down the bootcamp partition within Fusion, and try shutting the IMac down again - but to no success - I still get the mouse freezing when I try to select the bootcamp partion at boot-up time.
Any ideas?
By the way - I've been using OS X 10.5.2 from day one, and I've been using the latest version of Fusion 1.1.1 since day one.

To answer my own question - it was actually an external DVD USB drive that I'd introduced. If it's powered on when I boot up, then Windows freezes (even though the drive is empty). If I power it on after XP boots up, then everything is OK.....!
How strange.

MAX shows PXI card when booted into Windows but not in Hypervisor mode

Hello again all you helpful forum-goers!
I'm having some difficulties with a Hypervisor system seeing the two Pickering 6 channel programmable resistor cards that are loaded into the PXI chassis. When I boot into Windows mode, MAX sees them under the My System just fine. When I then run the Hypervisor configuration software, I see them both listed, and have them assigned to the Real-Time OS. However, when I then boot into Hypervisor mode, MAX does not see them under the Remote Systems -> Hypervisor Target -> Chassis (or anywhere else), and the drivers report not seeing any modules either when I debug my code running on the real-time system.
Does anyone have any idea what setting or configuration I might have incorrect? Is there any other information I can provide that would be relevant or useful to answer this question? I'm not the main hardware guy, he just got married and so isn't available, so I'm out of my comfort zone. ;-) I write the software that runs on the system, though, so I'm not completely clueless. I know we just replaced the controller in the main chassis with a faster one (unfortunately I don't have the number on hand, the simulator is down in the lab), but I also know we are using that same controller and Pickering card on a different simulator and it is working just fine.
Any ideas? I very much appreciate your time!
-Joe
Solved!
Go to Solution.

Nevermind, the answer turned out to be that I did not have the drivers fully installed on the real-time system. Apparently that caused it to not recognize the cards. I never did figure out / remember exactly how to install the Pickering drivers on the real-time side, but fortunately I was able to just copy all the files that had "Pickering" in their name from the C:\ni-rt\system folder of the real-time file directory from another simulator to this one. ;-)
Cheers!

(SOMEWHAT SOLVED) grub2 finds and boots windows 7 but NOT arch

I installed arch on a new system. I have 64-bit Windows 7 Ultimate. I installed arch skipped bootloader, chrooted into system and installed grub2 and installed. My system is btrfs. I do not have a seperate swap or home partition. OS-prober is installed. I have another system with btrfs and grub2 and all works fine. When I run grub-mkconfig -o /boot/grub/grub.cfg I get this
Keyboard is not working properly on other computer so I cannot insert code brackets.
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
No volume groups found (what does this mean)
Found Windows 7 (loader) on /dev/sda1
done
Again boot and root partitions are btrfs. Grub2 is the bootloader and it does support btrfs at least the version in the repos a month ago did. I have feeling this might be the problem but I do not know why. Windows 7 boots successfully by the way. No Arch Linux
Edit: Backed up boot partition. Made the partition ext4 and cp'd it all back and still no luck. I converted it because ran the grub-mkconfig again and I got everything above but also I got an unknown filesystem error. Converting it back to btrfs...
Edit 2: I am writing this from within windows but grub2 now shows Arch in the the menu. (no gui on this install yet) After what feels like 100 grub-installs and grub-mkconfigs it is all working. I still have two questions. For like half a second I see a file not found and I think it is a *.mod in /usr/lib/grub/i386-pc directory. (i have good eyes). What could this be? Secondly, what does no volume groups mean? Marking this somewhat solved.
Last edited by quasifilmie (2012-03-30 23:59:43)

I'd just ask checking the grub.cfg file to see if the device id entries for arch in the grub menu are correct.
In my case, I use ubuntu's grub2 and each time I have to update grub for some reason, it wont get the partition right for the arch entry.

Three beeps booting from cd but not regular boot up?

I have a good number of bad sectors on the internal hd of my Macbook Pro, so I want to run disk ultilty/repair from the Snow Leopard boot cd. Trying to boot from the cd (either by pressing "c" or pressing "alt" and choosing the cd on startup) shows the Apple logo but goes no farther, and produces a repetition of three beeps. Looking at other posts it seems that three beeps are an indicator of bad memory, but why would I not get the beeps on regular startup (not booting from a cd)? Does the three beeps mean something else in this situation? Any help would be greatly appreciated.

If you are now running Lion boot the computer and hold down the Command+r keys. That will boot you directly to the Lion Recovery HD partition. That is IF that partition is still on your internal drive and it can be booted. As you say the drive is showing errors it may not boot properly.
In the case that it doesn't boot to the Recovery HD you can use Internet Recovery. That is where your system is booted from over the internet.
Hold down the Command+Option/Alt+r keys until you see a Spinning Globe in the center of the screen. Once that has loaded you can use Disk Utility to check the drive and repair it if it can be repaired. Or you may need a New drive if it can't be repaired.

Booted from ICHAT, but not AIM

Just started up a new wireless plan with ATT and been using a wireless router...When I do not restart my router every day I consistently get kicked off ICHAT every 3 - 15 mins unexpectedly with a message stating something like, HOST cannot connect to server. During this time my internet is working perfectly ok. When I power on/off my router Ichat will work fine for the remainder of the day, but must be powered on/off the next day.
On XP through bootcamp, I have not powered on/off my router and I do not get kicked off AIM or have any internet troubles. The internet service provider said my router looks fine as well as my signal........

Swollen Battery - but not in recall serial numbers?

Hi,
My battery on my macbook pro 15" 2.16ghz has swollen and split at the corner by the power connecter. It also seems to have bent the bottom of my mbp on the edging by the memory slot cover? I bought my mbp in June '06.
I checked on the Apple site and it said it wasn't part of the exchange program. Is it still safe to use? I have taken in out for now but I am a teacher and use it in most of my lessons and don't always have access to a plug socket.
My battery model and end of serial no. is A1175 & GW2TA. Anyone else had this problem?
Cheers

Nice for you Jonsey3... I wish Applecare were quicker in sorting out my dead battery.
I logged a case on the 2nd Jan and my replacement battery is still, as of 7th Jan, "Parts Shipment Pending".
I'm tied to a power adapter until the replacement battery arrives as my battery isn't recognised at all by my MBP.
Uncool Apple, uncool.

My i5 is water damaged.....will boot with logo but not operate. I wish 2 sell, but must wipe data first. Suggestions?

Not operate?
Try this... tap Settings > General > Reset > Erase All Content and Settings
If that won't work, then you won't be able to delete all the deta.
Rather doubtful you can sell an water damaged iPhone ...

My ipod 5th generation charges when connected to my PC but not recognised in itunes with windows 8.1

Why is my ipod 5th generation not recognised in itunes in windows 8.1?Connection to my PC only charges the battery.

Did this iPod previously work with this computer (running Windows 8.1), and does not now for some reason? Or is this the first time (or the first time with Windows 8.1)?
The fact that only the battery charging symbol appears on the iPod screen seems to indicate that the iPod does not recognize a data connection. It's like you are connecting the iPod to USB (wall) power adapter. It is likely that the Windows system also does not see the iPod as a connected device; you should confirm by looking at Device Manager.
You should rule out a faulty USB docking cable. The dock connector has separate connection points for power and data, so it is possible for it to connect to charge the battery but not connect for data. So, if possible, try another docking cable, or try the cable you have with another Apple device.
You should rule out a problem on the USB port. If you connect something else to the same port, does it work properly? Preferably, you should use something similar, like a USB flash drive or port-powered external drive, and try copying over some large files.
If the USB port and docking cable are OK, the cause is more likely to be on the iPod (such as a dock connector that is worn out from use).

HP ProBook 4540s slow to boot up, all programs run slow, long delay, show non-responding messages

Hello,
I have a HP ProBook 4540s running windows 7 (desktop shows: Test Mode Windows 7 build 7601)
The HDD is a Toshiba mk5061gsyn 500gb
For the last month or so the computer has been running very slow. The computer has always booted/start windows a bit slowly. Now it takes about 3-5minutes to get to the welcome screen then it takes a couple of minutes to load windows. Soluto shows all the programs that are being loaded on startup. (I never messed with this). I've run several antivirus programs and the system is clean. Back in June I had the same problem but there was malware found, not this time.
I ran speccy and it shows "warning" under the S.M.A.R.T section. I used the HP system tools and ran the HDD test and no errors were found. When I tried using the HDD test from Toshiba and I couldn't run the scan test, it only showed the model name and serial #.
I'm not sure what to do next?
Thanks for your help in advance!
