MacBook Pro :: Super Slow Boot / Can't Find Bootable Device?

May 5, 2010

So earlier after installing a windows 7 ultimate 64 bit RTM copy into bootcamp, things started acting up;

After installing some updates for 7, rebooting, it took about a minute to get the HD icons up to even choose one, and after that it was fine, except then the windows partition eventually just had a blinking cursor in the top right and stayed there.

I went into OSx, removed the 7 partition completely! my HD is one partition for Osx, but when I boot now, it takes yearsssss to just boot to osx, but if I hold option, then I instantly get a Macintosh HD (that's it) and it will go straight away.

What do I need to do? Reinstall SL? Please god no.

Partitions seem to be all messed up, maybe I will re create a windows install, and remove it again. (Xp this time)

Edit, This happened on 2 different MBP's one a 2.8 duo after I put on 7, they both take forever to boot to OSx. (With no BC partition even on)

MacBook Pro :: No Bootable Device Found / Insert Boot Disk And Press Any Key

Sep 1, 2014

Not only will holding Option while booting not work, but all of the other boot tricks (safe mode, single user mode, etc), will not work. I am at a loss. I also don't have an optical drive in this particular MBP. I have an SSD where it once was.

Windows On Mac :: No Bootable Device - Insert Boot Disk And Press Any Key

Nov 27, 2010

I always get this error when I try to boot up to my Windows on Bootcamp: No bootable device -- insert boot disk and press any key

I installed Windows 7 through Bootcamp and I got everything installed perfectly!
I partitioned my Mac's hard drive into 3 before the Windows installation:
-Mac OS
-Data For Windows
-System for Windows itself

It all worked fine and i could drag and drop anything into that Data Hard drive through Windows very easily. However, when I came back to my Mac OS and partitioned my Mac Hard Drive into 2 parts(Which makes 4 partition now) and tried booting back up to my Windows, it gave me that error. I then decided to re-partition it like before which was Mac, Data and Windows. Booted it back to Windows and it gives me the same error again. I have an attached Picture showing how my partitions look now. Does anyone know how to fix it? I think it's because what my Windows is booting from is the Data Hard Drive but not my Windows 7 Hard Drive with the OS on it. Is there a way to change it's place or to tell it which Hard Drive to boot from?

OS X :: No Bootable Device After Bootcamp?

Nov 21, 2008

I tried to install ubuntu with bootcamp on a different hard drive. Something happened and now when I turn on my computer it says no bootable devices. It doesn't even see my OSX hard drive. I tried booting up my computer and holding down option. It doesn't work. I have a wireless microsoft keyboard. Is it not letting me hold down option because the computer finds the wrieless keyboard to late. Some one said u have to hold down the option key before the mac sounds happens. The keyboard lights don't come on till after that. Should I get a USB keyboard? I have to press the start button on the keyboard to act as the option key when I'm in osx. Would the computer know that the start key is the option key on boot up?

MacBook Pro :: Super Slow Wireless With New Router?

Jul 9, 2008

So I recently bought a Linksys WRT160N to replace an old router in my house. The network worked fine with the old router before it died... Browsing speed was great, download speed was great. Now that I have the WRT160N however, my network speeds have plummeted. And it's JUST my MBP... the rest of the computers in my house are Windows PCs and they are surfing away at supersonic speeds compared to what I'm getting on my MBP.

At first I thought it may be the wireless security (WPA) so changed it to WEP... no change. So then I just disabled it altogether... no change.

The Windows PCs are getting speed of about 2000 Kbps whereas I'm getting between 150 and 500 Kbps. I've already replaced the router once...

Is there anything I can do, or is this router just not going to play nice with Mac?

BTW- I have a 2.2 SR MBP

Windows On Mac :: BootCamp - No Bootable Device Error

Oct 19, 2009

I first installed Windows XP when I got my early 2008 Mac Pro. Boot Camp was probably beta back then, but I cant say my experience has changed much through Vista 32 bit or now Windows 7 64 bit. The way to dual boot, holding ALt during boot, has worked 1/10 times. Literally. The boot symbols are usually delayed, so I know when I choose the win partition, it gives me the "No bootable device" error. Two times have I had heavy OS X crashes after these boot-up "games". This last time I had to completely reinstall OS X (or upgrade to SL). How could this be, im not even booting into OS X when I am trying to boot into win.

I even have a separate hard drive for my Win partition. Not to mention the stream of driver issues you encounter when you finally manage to get inside Windows. I actually had my apple wireless and mouse working in Windows 7, but then I installed Boot Camp drivers of the DVD, and now theyre dead. I know. Its Windows, why would I miss it? Gaming or apps, regardless. Apple shouldnt include a program that functions so poorly, if they insist on higher standards elsewhere. It only reflects badly upon them. I consider myself a decent level mac user, venturing into command line troubleshooting if needed. But BootCamp remains a mystery to me.

Mac :: Cannot Install Windows Cd - No Bootable Device Found?

Jul 16, 2010

I have this student's laptop who's hdd was corrupted as. Only 10% worked, able to slightly read through external drive reader which took ages to read. Couldn't get testwin or chkdsk to repair it (under windows)Anyway, got him to replace the hdd and he also wanted windows on there. Either XP or 7 on there.Upon trying to boot from the windows 7 or windows XP disc, I get "no bootable device found - insert boot disc and press any key"Thus tried booting while holding C down, and tried booting while holding "option" down", problem is..i think his bios is corrupted as well. I get a white screen upon powering up. No mac logo. When I hold down "option", the mouse arrow pops up but nothing to click on.

OS X :: Internet Is Super Slow, Restart Fix It?

Nov 2, 2009

For at least 24 hours now the internet has been incredibly slow on my Alubook. By super-slow I mean 10-15 minutes to load MacRumors. I was sure it was my connection, until I today tried it on my iPhone on the same WiFi network. Took a couple of seconds to load.

So I then thought Safari might be the problem, but I found it was equally slow in Opera and Firefox.

Intel Mac :: Goes Super Slow And Doesn't See HD

Jun 14, 2012

But today when I started my iMac he first didn't show my external hard drive so I thought maybe my hard drive is broken so I tried instead of FireWire an USB cable but that didn't work either. So I tried connecting it to another computer and it worked so the problem must be with my Mac somewhere. 

Now my Mac goes extremely slow and when I do 'Shut down' it takes minutes to get him powered off completely.  

Now after a few minutes my Mac sees my Hard Drive again but the Hard Drive usual Icon isn't showing and when I open it to browse through it, it goes extremely slow. It looks like he is initializing everything on my hard drive, so I can't copy or open anything that is on it because it goes so slow.

Intel Mac :: Its Running Super Slow

Jun 16, 2012

Got a 21.5 inch iMac desktop summer of 2010. I think it is the base model. All other info I can't get to on "about my mac" because my Mac is running like frozen molasses.

Anyway, last few days I thought the internet/Safari was running kind of slow. Pages would load, I'd get stuff done, but I just thought it was being glitchy. Then last night, my Mac would all out freeze. Rebooting took at least 5 minutes, and it doesn't matter what I try to use (chrome, firefox, safari), pages just won't load at all or freeze if I am able to make it to Google/Facebook/etc. Now the computer just sits at the blue screen part of the startup, and I had to just finally hard shutdown since I am not getting anywhere to even run a virus scan.
