The system will not boot

Hello, I am trying to install windovws after the restart can not install Yosemite because can`t please format the hard disk.Please help because just yesterday bought macbooc

FYI...the top partition is too full. You need free space. You will need to remove the bottom partition then make the top partition larger. Make sure you have 10% or more free space. If you use Parallels or VMware you don't have to partition your drive. If you use the vm software you can run Windows wihtout having to reboot into bootcamp each time you want to use it.
See this link for help after you resize your top partition.
https://www.apple.com/support/bootcamp/
I forgot to ask...
If the system will not boot, how are you seeing Disk Utility. Are you booted from the Recovery Drive? If yes, then you will need to erase the internal drive and reinstall Yosemite on the internal. When you erase, make it one partition. You can add a second partition later that's smaller.
Note: you posted in the OS X 7 Lion instead of the Yosemite forum. In the future, asking on the correct forum gets the best answers.

After System Update last night, the system will not boot with IOPlatformExpert.cpp:1504 error

I have had Lion for a 2, 3 months on the iMac 27 inch purchased last October (2011). Last night I chose to update the system, and deselected iMoves update because it was 1GB, and chose only 4 updates, including iTunes, Safari (i think)... But the update says error, and ask to restart the system (it won't restart itself, so I waited 30 minutes, and then pressed the Power button for 10 seconds, to let it power down, and press Power again to power it up).
However, after that, the system failed to boot up, showing a
panic(cpu 0 caller .....)" "Unable to finder driver for this platform: \"ACPI\". ... xnu-1699.26.8/iokit/Kernel/IOPlatformExpert.cpp:1504
This is not typical of the upgrade process. So I searched the Internet forIOPlatformExpert.cpp:1504 and some people said it is a hard drive error, but then I powered down and pressed Options when booting up, and was able to boot to Windows 7 (bootcamp)... and was able to boot to the "Recovery", which let me choose

what should I do now to fix it so that it can boot again?

This error is caused by one of the updates you applied, namely the Thunderbolt Software Update 1.2. Many people have been affected by it, including me. I did what Linc Davis has suggested above to fix it. The most extensive discussion about the problem, with ways to fix the problem, is here:

Hi
This may be a disply issue try to connect a external monitor to your notebook and see if you get the display there.
You can connect to an external monitor via a VGA or HDMI connection. The usual process to transfer the video output to an external source is to hold down the fn key and press f4. Use the arrow keys to select 'Projector Only' and hit enter.

System will not boot up

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.

Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine.

System will not boot with Seagate 3Tb expansion drive plugged in.

I have a HP Pavilion HPE h8- 1214 Desktop , I recieved a Seagate 3TB expasion drive as a gift but when plugged in, the system will not boot. It turns on but thats it. It never gets to the boot sequence. I have it plugged into the top 3.0 usb slot and have tried all of the other slots as well with no sucess. But if I leave it unplugged the system boots right up. I can then plug it in and it works fine. I have plugged it into my wifes HP All- In- One and it boots fine and works. I have a WD 2TB drive that works fine as well on my system . I have searched Segates support for hours and all they say is to change the boot sequence. Have tried that, no go. What they dont get is no matter what I do if that drive is plugged in it never gets as far as booting and reading the boot sequence. Please help. Thank you!

Hi NcBunky,
Are you using Win 7 64 bit? Did you update the Texas Instruments (TI) USB 3.0 XHCI Host Controller?
I have an H8 1380t PC. Updated the TI USB 3.0 driver and had the same problem.
When booting the PC with the USB 3.0 external drive connected to the PC the PC would not boot. When booting the PC with only the mouse, keyboard, and a USB 2.0 external drive attached the PC would boot. Once booted you could attach the USB 3.0 drive and it worked fine.
Solution was to roll back (reinstall) the TI USB 3.0 XHCI Host Controller to the original factory installed driver.
System now boots with the external USB 3.0 drive attached.

When i install a 2nd 1gb stick of memory in my pavilion dv6000t laptop, the laptop will not boot.

HP Pavilion dv6000t running Windows Vista Ultimate 32-bit version. My system currently is running on a single 1GB stick of memory. I have a 2nd matching 1GB stick of memory. When I install the 2nd stick of memory the system will not boot. All the lights come on, the hard drive spins up, but you can not even get into the BIOS setup screen, it just sits there with a blank screen. What could be causing this. Thanks in advance for any assistance you may be able to provide.

Hi:
When I encounter issues like that, I switch the memory modules to see if one of the chips is bad.
So, I recommend you remove the one memory chip that is working, and put the other one in its place.
If the PC boots up, now install the second chip and see what happens.
If it doesn't boot up, then there is some undefined hardware issue.
If the PC doesn't boot up when you initially switch the memory with the one stick, then you know that the one memory module is bad.

Reset CMOS, system will not boot

This is a long story but I will try to keep it short:
I just bought a new 875P Neo-FISR and a 3.0 GHz Prescott, which from reading the other posts could have been a mistake. I installed the CPU, memory, and the video card and pressed the power button and received a "CMOS Data Wrong" error. So I tried to correct the problem but when I saved and exited then the system would not boot back up. So, I reset the CMOS via the jumper and tried again. After MANY attempts I change just the month in the date setting. And what do you know...it would not boot back up. The D-Bracket LEDs were: 1-flashing red/green, 2-flashing red/green, 3-red, and 4-red
I must have read almost every post in this forum and tried many things such as:
disconnecting all componets except for video, ram, and cpu
the during boot to recover the BIOS
removing mobo from case, maybe a short
moving the memory to different slots
moving the PSU to a different computer...it works
disconnecting the PSU from the mobo and and removing the battery overnight. The first night I did not disconnecting the PSU from the mobo and I found that did nothing.
Tryed everything that I could think of and some stuff that others thought of but nothing worked. However the last item...removing the battery...did change things some. Now nothing happens, and I mean nothing...no lights, no fans, no buzzing...nothing.
Any ideas would be greatly appreciated. The only recourse I have left is to RMA the board.

I tried one stick in all of the slots with and without the sound card. That did not work either.
The voltage for my memory is 2.6 so that is what I tried. But if I can get it to boot up again I will try 2.7.
Tks.

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.

System will not boot - Arrives at 'Bluetooth Setup Assistant popup &

A Bluetooth Setup Assistant (BSA) pop-up arrived on my screen looking for bluetooth mouse (which I do not have). It is in front of the log-in screen (I can just see it behind the BSA pop-up). I cannot get rid of it. The keyboard and mouse will not work and i cannot reach any of the system tools as the system has not booted. I tried (a) shutting off & restarting. But it always arrives at this same screen. (b) safe mode start with same result. (c) Command Option PR start with same result. (d)Then put in installation disk to start from disk (Holding down 'C') with same result. Now my installation disk will not eject (holding down mouse button on startup). (e) Also tried startup with firmware (Command-Option-O-F) with same result.
Can anyone help get me round this original problem as well as finding a way of ejecting the installation disk?

Note: I assume in the following that your mouse & keyboard are standard USB wired devices -- if not, please say so. Also, if yours are not Apple branded devices, please mention that too.
It sounds like your keyboard & mouse are not being recognized as connected to your Mac so the OS is looking for Bluetooth devices as an alternate source of user input. If this is so, what may help is to unplug them & plug the keyboard into a USB port on your Mac (not on a USB hub attached to it) after restarting, when you see the BSA screen.
If this doesn't work, try unplugging all other USB devices & repeat the above. If that doesn't work, you may have a defective keyboard or mouse. Check for that by substitution.

I have an HP Officejet Pro 7580 similar to the 8600 you have and after upgrading to Mountain Lion it wouldn't work. HP support site said download updates for Mountain Lion from App Store not their site so I went to software update but there were NO UPDATES FOR 10.8. Tried a million things and could not get printer to work. So I restored back to Lion figuring at least printer worked then only now I can't get it to work with old settings either. I am sick to death of claims by Apple and peripheral manufacturers that everything is compatible all you have to do is get updates well in this case THERE ARE NONE TO BE GOT and I don't have time to **** about trying to find 'work arounds'. There shouldnt be a need for work-arounds. Unless the updates are ready DONT release the new OS. You shouldn't have to be an IT tech to make basic things like printing work. I see also the HP 8600 is even sold by appstore so there is no reason why it shouldn't work with minimum fuss.
