It won't get past the grey start screen.

I had a new logic board put in last year. Now it seems like it running hot fan spinning and just sits on start screen before you see the logo. Any ideas on what to do. I cooled it off. Unplugged it. Removed the battery and still same result.

I'm having the same problem everynow and then... I'm running mac osx lion. I have reinstalled lion to see if that will work. now it is starting again but not sure for how long. The problem is that I'm getting small interruptions while running itunes or a movie... it's a like a second cut every minute or so... strange. Never had any problems before.
If it keeps on behaving weird I'll do a clean install.
I suggest you run disk utility and AHT (apple hardware test) before you do anything, AHT should be in the CD you got when you purchased your machine and the disk utility should be initiated by holding option while booting (chose recovery HD if you're running lion). Hope that helps.

Macbook won't get past the grey start up screen

I purchased my Macbook in 2008, roughly July.
My fiance unknowingly shut down my macbook in the middle of start up. Before that it was running perfectly fine, I had no issues.
After my fiance stopped the start up, the macbook won't turn on. It'll load up to the grey loading screen (example here)... It doesn't make much noise as it starts up either. I have all original discs that came with the macbook, if that helps any.
I'm frustrated, as I can't afford to replace my mac at this point.
Any idea what I can do?
Thanks..

Hopefully, nothing permanent. Do the following:
If you have Snow Leopard installed:
Reinstall Snow Leopard without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
If you have Lion installed:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
If you have Leopard installed:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

A1226 won't get past the grey loading screen

I just purchased a macbook pro model A1226 from a friend who said it wont load up OSX. I figured it was just a hard drive replacement and wouldnt be a big deal, but I swapped the hard drive out for another and it still wont load. I went to put his back in. He said it had Lion on it, but when I held the option key down to go to the recovery drive, the regular startup drive says leopard.... so, not sure what i'm working with. I've tried to look on here and find different options to use at startup. I have my old snow leopard family pack install disks, but everytime I try to boot to the disk it trys to then gives me a "you need to restart your mac" prompt. I've tried resetting the pram , I've tried to get to this ever so elusive apple hardware test by pressing d prior to startup etc. and i'm at a loss. Please help. Thanks.

Boot holding down the OPT key. That will start the boot manager and you can see what your options are.
Edit: sorry, missed the part where you'd already tried that.

I can't get past the grey apple screen using mavericks

I can't get past the grey apple screen trying to boot up with Mavericks. I had been using Mavericks for about a month (only had issues of freezing occasionally). I read in one of the posts here that I should try holding command R down when booting. I did now I just get a grey screen without the apple. Any advise?
I have a Mac Mini

Hello ther cnickers,
It sounds like the initial install of Mavericks went ok, and you have been using it for a while, but now cannot boot to your desktop and are stuck at a gray screen with an Apple logo. I would recommend a couple of things here:
First, try performing a Safe Boot to see if that will load up for you. If so then leave Safe Boot and restart from the Apple menu to try and get to your deskop:
To start up into Safe Mode (to Safe Boot), follow these steps.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without holding any keys during startup.
From: Mac OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/ht1564
If that works fine, I would next also verify and repair your disk if needed.
Disk Utility 12.x: Repair a disk
http://support.apple.com/kb/PH5836
Print this help page so you can refer to it later. (You don’t have access to Disk Utility Help when you restart up your computer in the next step.)In the Disk Utility Help window, choose Print from the Action pop-up menu (looks like a gear).
Choose Apple menu > Restart. Hold down the Command (⌘) and R keys as your computer restarts.When you see a white screen with an Apple logo in the middle, you can release the keys.
Click Disk Utility, and then click Continue.
In the list at the left, select the item you want to repair. (Be sure to select an item that’s indented to the right in the list, not an item at the far left.)
Click First Aid.
If Disk Utility tells you the disk is about to fail, back it up and replace it. You can’t repair it.
Click Repair Disk.If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. Otherwise, you may need to do one of the following steps.
If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. Check each file in the list of affected files. If you can replace a file or recreate it, delete it. If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted. (Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.)
If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall Mac OS X, and then restore your backed-up data.If you continue to have problems with your disk, it may be physically damaged and need to be replaced.
Thank you for using Apple Support Communities.

My macbook air won't get past the white apple screen. I've tried power cycling the batter but won't help

my macbook air won't get past the white apple screen. I've tried power cycling the batter but won't help

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 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 11. 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.

My G-5 Won't go past the Grey Apple Screen......HELP HELP HELP

Power Mac G5 Dual Processor Mac OS X (10.4)

Hey Cris
I just got thru the same problem. My G5 was only 30 days old. I contacted Apple and after many phone calls I ended up purchasing the Applecare.
The parts were on back order for two weeks and they ended up replacing the logic board and the processor.
Good Luck!!!

How to get past the grey start up screen after mavericks update

I have recently installed a free update of Mavericks on the App store. However after installing this, the Macbook Pro that i've installed on will not boot beyond the Grey start up screen. I was running Snow Leopard on a machine with intel core 2 duo processors 4 Gb of RAM and over 100Gb of free memory.
I have attempted a safe boot (holding down shift while while holding the power button down), and Reseting the NVRAM by pressing 'command', 'option', 'P' and 'R' at the same time.
I do not have an installation disk or a time machine back up.
Does anyone know how to get passed the Grey start up Screen?
Any Suggestions would be mucho appreciated.

Curve 8900 won't get past the T-Mobile screen on start-up

I am hoping that someone out there can help. My T-Mobile BlackBerry Curve 8900 does not make it past the T-Mobile screen on start-up. The battery was fully charged when this happened. Personally, I think it has to do with iHeart Radio crashing, but I could be wrong. I have tried to plug the USB cord into a rear port on my laptop and launch the Blackberry Desktop Manager to see if I could do anything, but nothing happens. The BB Desktop Manager does not connect to the phone, because it is not getting past the T-Mobile screen on start-up. Not sure what to try.

Hey VTX1300R,
Do you have a recent backup of you device? If so the you may want to try to do a reset to factory on the device. Have a look at this article to see how to do it. http://bit.ly/98bCNO

My G5 shut down + when it restarted it won't go past the grey apple screen

here's a general rundown of how I got to this point...
last yr the hard drive on my '05 G5 went, so i had it replaced (6-7 months ago) and for the last 2-3 months i've had problems with involuntary shut downs (cut to black) it started happening once a day and then there were days where it would happen more often and then less often and eventually got to a point where it was happening every 5-20 minutes, so i brought it in to get looked at and was told that it was the power supply that was malfunctioning. I mentioned that I would likely be buying a new mac in the coming weeks ( i did yesterday) and was told that I should be ok between now and then without having it fixed and then when i did get my new computer they would transfer all of my old data onto the new computer and would be installing the new power supply before selling it to a local school. then, 3 days before I was going to get my new mac, it shut off yet again, but when it rebooted it never went past the grey apple screen. after 4 or 5 minutes the fan comes on and is amazingly loud and this is where it stays until i shut it off. i'm not sure if this is simply the power supply finally going going gone or if this has something to do with the very new hard drive or who knows what else; i just want to get my info from the old computer onto the new and hopefully get the couple hundred dollars that i was told my g5 was worth. is there something i can do to get past the grey screen before i bring it in?
thanks in advance,
Jeremiah

I doubt that your data have been lost, the hard drive should be fine. Too bad that you're going to sell it, you could have used the hard drive in an enclosure to back up your new computer to. Please remember to make frequent backups/clones, I use SuperDuper! and it works perfectly. I have used it to re-clone a drive from the external when things have gone bad, you can also boot from a SuperDuper! clone.
Anyway, let us know how things go, I'm pretty sure your drive will be fine.

My emac won't get past the grey screen with spinning indicator

before i went to bed last nite it was fine. when i woke up i click on the screen and got the little rainbow ball. that lasted for about 5-10 minutes so i had to push the button. when i try to turn it on now it gets to the grey screen with the spinning indicator but won't get past that. any help would be appreciated

An Archive and Install will preserve you user settings and data. You will need a minimum of 5 GB free on the hard drive to perform an A&I; you can reduce the space required by about 1 GB by selecting the option to install language support only for the language you use (assuming you don't need multiple languages).
However, after seeing your other post (BTW, it'll be easier to keep track if relted issues are in the same thread), you do not want to try an A&I if Disk Utility is reporting anything about 'could not be repaired'. Doing so will would ensure problems down the road, if it worked at all. It's possible for one disk problem to mask another. Whenever Disk Utility (or any other repair utility) reports making repairs, it's good practice to repeat the repair until it reports no problems found or it becomes clear it cannot repair the disk.
DiskWarrior has an excellent track record at repairing problems that Disk Utility cannot (especially Disk Utility versions prior to OS X 10.4.2).
If the drive cannot be repaired, you may be able to keep it by doing an erase install with the write zeros (one pass) option. That will update the hard drive firmware record of bad disk sectors to avoid using. If there are only a few bad sectors, that may let you keep using the hard drive for several more years. An erase install will do just that to your data, through. If you have access to another Mac with either a large amount of free disk space of a DVD burner, you can try using the other Mac as host and the eMac as target in FireWire target disk mode. You can run the host's copy of Disk Utility on the eMac hard drive, and hopefully be able to mount the emac HD so that you can back up the data in your Home directory.

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.

Can't get past the grey loading screen with the apple

My ibook was working fine for a while and then all of a sudden I turned it on one day and the desktop came up but none of the icons or toolbars came up. I talked to a few people about that and they seem to think that is was the os going out of whack.
So, I tried to install tiger and when i did that it would only come up to the blue screen that said it was loading os x.
So i thought maybe it installed funny so I tried to reinstall it, but it wouldn't let me. I kept getting a bunch of different errors.
So now, when I try to turn it on it just stays on the grey screen with the apple on it and sometimes the apple goes away and turns into a white square that has dots and lines in it.
Can anyone PLEASE help me out???

Hi, and welcome to Apple Discussions.
Which model iBook is it? (What is its processor's MHz rating?)
Which version of the OS is installed on it now?
If OS X 10.2 or above is installed on it, you can try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if you are able to do a little hard drive maintenance to help things out.
I hope it works for you.

Computer won't get past the first boot screen after install

Hullo,
I've been meaning to try Linux for a good two years now, and finally got to the point where I will install it, and stick with it, and nothing else but it, for a month.
I decided to go with Arch, because I'm a minimalistic kind of guy, don't mind getting my hands dirty, and a few other reasons. So, I got a copy of the "release" version, arch-0.7.2-base.iso, I believe the same as the most recent stable edition from the nethat FTP.
I burned it as an image onto a CD-R, popped it into my CD-ROM drive and rebooted my computer. It came up, I hit enter to boot, it was successful so far. Then I got to the menu screens, where I did the easy part, and just erased my harddrive. Then I selected the base installation from the CD, installed it, seemed fine. I then installed the kernel and boot loader (GRUB) and everything seemed ok.
I type in reboot as it says, it reboots, the first screen pops up, where it says Gateway, Intel Inside, and press F10 for this, and F2 for that. It stayed like that for 5 or so minutes, so I restart. Same thing, restart again. Try to press F10 and F2, nothing. Restart again, same thing. Kept it like that, thinking it was a little laggy and had to do something. It's been on that screen for a good hour and a half now.

But like I've said before, I CAN'T get there. It stops at the first boot screen.

It won't get past the grey start screen.
