Hp Touchpad Grey Screen with stuck partial download?

Can anyone assist? After a recent download I now get a grey screen when I turn the machine on in the centre of which appears to be part of a map icon that does not work?
The touchpad seems to be working OK and I suspect its just a download thats gone wrong but I have no real idea.
Can anyone suggest how I can restore to the blue screen? Thanks

Gets stuck on grey screen with logo after restore.

I restored my 2008 macbook and reinstalled OS X lion onto it. It downloaded items for lion and automatically restarted. When it restarted it got stuck on a grey screen with the apple logo and a spinning circle. I turned the computer off and attempted to restart again, same outcome. I restarted it again and pressed command option p r (saw it from other posts on here) and it brought me back to the screen where I can reinstall OS X lion, go to utilities, etc. So I clicked reimstall lion and it did its thing and automatically restarted. Then like last time it got stuck on the grey screen with the logo and spinning circle.ugh! What am I doing wrong? Please help.

Restarted it again with the p r command option brought me to the installing screen again and then said "there was an error installing please try agian" please any help is aporeciated, I have my files on an external hard drive but I need to be able to access my computer so I can continue applying to jobs/access my resume on the external hard drive and it is my only way to talk to my deployed husband besides email on my phone.
I also clicked repair disk in utilities and it says "the volume Mac os x base system appears to be OK" It will not bring me to the thing where I have the option to reinstall lion. I restarted and its yet again stuck on the grey screen with apple logo and spinning circle.

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 startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Stuck on grey screen with apple logo when starting up?

Hi,
My Macbook (2009 aluminium unibody (Leopard 10.5.8)) won't boot. When I try to start it up it gives the chime and then gets stuck at the grey screen with the Apple logo and some spinning gear below. I have tried booting with the install DVD and repairing through Disk Utility but this doesn't work. Disk Utility can see the hard drive but none of the partitions on it! This makes me think the hard drive has died.
However, I can still boot to Windows through BootCamp. From Windows 7 I can still see and access files from the Mac partition. So maybe the hard drive is ok and something else needs fixing... SATA cable???
Other info:
The night before this happened my computer froze when trying to shut down from Windows and I had to force shut down.
The current internal hard drive is only about 4 months old (a bit short for it to be dying already - its a Western Digital 750gb 7200rpm). I replaced the old one as it had stopped working (at least i thought it was the hard drive ). The hard drive I replaced had lasted about 2 years (Seagate 500gb 7200rpm). Maybe the 7200rpm gets too hot?
Any help much appreciated as I really don't want to be reinstalling again.
Thanks

Boot from the OS dvd and start the install process, but stop immediately after the language selection. (You are not reinstalling.) At this point you will see a Utilities menu. Open Disk Utility, select your start up disk, and click on Repair Disk. When that is done, quit DU and restart.
See if that procedure will let you boot as usual.

Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
In other words, your computer can't talk to your operating system so you can't access your data.
Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
First: Shut down your computer completely
Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
Hope this helps, it's annoying but it's your safest bet.
All the best.

Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Leopard - This will install a "fresh" copy Leopard without archiving old system files but leaves the rest of your files in place.
If you still want to restore your computer to factory level...
Start up from your install disc, go to Disk Utility and select the disk and click erase - to securely erase data click Security Options and Erase Free Space which will entirely wipe your disk, overwriting it with zeros so that no data is recoverable.
To restore read the instructions in the Mac OS X v10.5 Leopard - Installation and Setup Guide PDF

MBP (2010) stuck in grey screen with Apple logo no matter what I do.

Hi everybody,
I know this issue has been posted many times in the past, and I have searched everywhere, but I am quickly running out of option but to repartition/reformat and do a clean install. I have important files on my computer (I know! Back up! Back up! Back up!) and need your help to preferably regain full access to my system or somehow find access to my files so I could transfer them to an external hdd.
From two days ago my as I was browing the net through Google Chrome my computer all of a sudden started to show the sippinig beach ball and became completely unresponsive. I could not force shut down any program or restart the system. So, I held down the power button and forced the system to shut down. When I rebooted the MB it all began going haywire. The boot process gets stuck in a grey screen with the Apple logo and the spinning wheel (not the beach ball) for a long time. After that I get the mouse pointer, and if I move that it turns to the spinning beach ball and nothing happens except that the screen flashes between silver and grey colors.
So here are the steps I have taken as to "attempt" to fix the issue (I have followed these instructions: https://discussions.apple.com/docs/DOC-3353) :
1. Went into startup manager and ran the disk utility to verify disk volume and permissions. Everything seems to be OK.
2. Conducted a PRAM reset. No change.
3. Conducted a SMC reset. No change.
4. I did a fsck -fy run (in command mode) on startup. No change.
5. Ran the system in verbose mode and got the following error: "BootCacheControl : Unable to open /var/db/BootCache.playlist"
6. And lastly, I created 10.8 OSX image on a USB stick and reinstalled ML one more time only to get stuck at the same place yet again.
Additionally, I can see my computer from my wife's MBP also running ML for a while. The folder that I have set the permission to be available, I can access! I have moved some files, but naturally the files that I want are in folders that have restricted network access. That just tells me the hard itself should be fine (perhaps).
I am running out of ideas fast to save the system. If anyone can help me, I'd be immensely grateful. Thanks.

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
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
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.
Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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 damaged 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 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see above for instructions.) 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 produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to 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.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
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 backup.
Step 8
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.

You should really read the manual.
"How do you restore from backup? "
Restore. When given the choice, choose to use backup.
"And how can I check to see if the pics and videos are on my computer somewhere first??"
They would only be where you put them. What program did you use to import them? Pics/vids taken with ipod are not part of the sync process at all. You should be importing them just as you would with any digital camera.
If you did not import them, then they are not on your computer.

Memory 8 GB 1333 MHz DDR3 ECC
Graphics ATI Radeon HD 5870 1024 MB
Software Mac OS X Lion 10.7.2 (11C74)
This is a brand new machine that I just purchased from Apple. It was delivered yesterday
The old computer is an old PowerMac G5, but my OS X install disc is a retail version of 10.5.
I also tried the OS X 10.5 install disc that came with my MacBook Pro (2.6 Ghz Intel Core 2 Dual).
Same issue - nothing but a grey screen when the system tries to boot from the DVD

Hi,
I had the power supply connected when I attempted it previously but even so my problem occurred. My rom is different and so I still need to update it.
Thanks
I wanted to mark your answer helpful too but I didn't know that I could only put it for 2 answers. Sorry
That was good advice by G-N and s/he is correct about it. Unfortunately, ASC allows only 2 "helpful" and 1 "correct" marks per thread.
