Bootable Device Trouble?

Hi Guys
Recently I tried to install Windows 7 onto my Intel based iMac. I aborted the procedure after first not being able to get past a black screen after the second installation reboot and second, after correcting this problem by searching the internet and finding that you can just delete one file, turned on Windows 7 only to discover and error box and an option to retry the installation(so deleting this file ment I was able to see what I was doing but was not able to actually boot the computer fully) (The error box came up after the spinning windows logo coming together) (help would be appreciated with this query as well). I deleted the Bootcamp partition (hence wiping all Windows data) and continued to use my iMac as it should. However I found that as soon as I turned it on again the following morning it booted to a black screen with Windows error text saying "No bootable device found. Please insert your install disk." Luckily I knew about the "Alt" key boot procedure and rebooted while holding the Alt key. (Please note: The Black screen came after the 'Buuuuuuummmmmmm' that OS X makes while booting) So its possible to use my computer but annoying to turn on. So please how do I fix this? (also how do I install Windows 7 successfully)

Glad it helped.
All the BootCamp gurus hang out in the bootcamp forum:

There may be more help there..

No bootable device installing w7 w/ Bootcamp and external DVD reader

Hello¡ Good night!
Lets see if anyone can help me find a solution since google, youtube and forums cant. (Wanted to call the apple support, but since my mac is from 2010, they want me to pay 19 S)
I have a MBP 17 inch from mid 2010, with MC OS X 10.6.4.
I installed Windows 7 like 2 or 3 years ago.
Everything was working fine, didnt give a single problem. Installed it easy by doing the partition and then with the original copy of Windows 7 32 bits did it quite easy and fast. (with bootcamp)
I used Windows and mac for all this years.
Last week, I decided I wanted to format my windows partition (since it was full of trash).
I had with me my original copy of windows and the installation of mac drivers (the same cd I used to set the drivers after the first intallation. Its the original, came with the mac).
I deleted the partition from the windows on the Boot Camp assistant, and re did it. And then the nightmare started.
After I prepared the partition from the bootcamp assistant (its the 3.0.1) I select the install windows now. Then the cd dvd from my Mac Book Pro started running but after a while it shut down, pulled out my windows cd and a message on screen saying , insert an original copy of windows and click yes... .. After trying for a while I decided to put in another cd, which was doing the same. Discovery, the cd,dvd from my MBP was broken. I checked up online to see if there was a problem and I discovered that this was not something new. A lot of people was having troubles with their optical drive stopped working out of nowhere and the only solution was changing it. Thing I cant do right now, since just that costs 120 euros...
I readed in some forums that you can use an external CD DVD reader so I bought one for 20 euros (Samsung SE 208A) which works perfectly fine in all the computers, even the MC OS X reads it and I can use it perfectly.
I put my original copy from windows 7 on the CD DVD, and click start windows installation in the Boot Camp Assistant. Which just reboots the computer perfectly.
And when the windows installation is supposed to start I get a message
No Bootable device... Please insert bootable device and press any key.
I tried all the solutions I saw online, nothing worked.
Pressing Option key while startup only opens the MacintoshHD
Pressing Option key with MAC OS X installation CD and then changing it to windows. (Windows cd appears on the bootable device, I select windows and I get back to the same back screen . No bootable device)
Pressing C and selecting Windows (From the CD DVD) and restart.

Thanks for the answer, but I dont have the windows anymore...
._. I have been reading a lot of forums (which is being hard, since everyone seems to have problems and not answers).
We managed to downdload a tool called rEFIT and we are now being abled to select the windows cd, but it's giving still problems. (Changing the list data from boot camp allows it to detect other boot routes) <- starting to feel like a hacker...
But we are still stucked.
We are trying to update my Boot camp to 3.1 (that seems to solve that problem) but for now it's being impossible, everything in the apple download website are .exe, which are the drivers ONCE you have windows INSTALLED. Clicking to Upgrade Software doesn't upgrade it.. So I'm looking into it...
I'll keep you guys informed if we manage to solve it.
Thanks for your time!

Help undoing Boot Camp Windows 7 install -- "no bootable device"?

I think there's some residual stuff from a Boot Camp install I need help getting rid of. Let me explain what happened so you'll understand what's wrong:
Ok so I set up Boot Camp utility to partition a 32 GB partition for Windows. I have a 250 GB hard drive, but when there were 32 GB in the Windows partition Boot Camp utility said that it would allocate 200 to Mac. I didn't really think of it, but what happened to the other 18 GB? Anyway, I tried installing Windows 7 (64 bit). After it installed, I was having trouble installing the boot camp drivers, so I decided to scrap Windows 7.
I shut down Windows and turned on the Mac, but it booted into 7. Weird. So I restarted again, this time holding the Option key, to get into Mac. I went into the Boot Camp utility and chose to restore the Mac partition and get rid of Windows. So right away it says it's done, okay. So now I check the Finder and it says I have 70 GB used, but I remember before it was 60 GB, so I wonder where that space went. And then I check iStat Pro and it says like I have 60 GB used and that the entire hard drive (including free space) is only 230 GB. Weird discrepancy, because Disk Utility shows it as 250 GB again...
So I restart the computer, thinking maybe it just needs to get its bearings. But it comes up with a black screen that says "No bootable device -- insert boot disk and press any key," and I'm thinking WHAT? So I power it off, boot by holding Option, and it only shows Macintosh HD.
So that's my situation, Windows still seems to be on there somewhere, but Mac doesn't know it, and I don't know what to do. Right now I'm erasing free space (don't know if that will help), but if there's a solution to this PLEASE LET ME KNOW.
I made a Time Machine backup before starting this whole process (thank God) so if I'm supposed to restore that in a particular way to get my hard drive back to normal or expect some things to not be restored or something please inform me.

I "skipped" the erase free space after reading your message, but it was already partly done. When I tried turning off the Mac after doing that, it seemed to freeze before completely shutting off so I forced shut down...
(I also opened the startup disk in System Preferences and clicked on Macintosh HD, I don't know if that made any difference.)
I zapped PRAM and now it booted like normal into OS X
So I looked into it, and actually the 70 GB seems to be in order (compared to the file sizes before backup, except for maybe a 400 MB Google Earth cache that seems to appear in my user library but not in the backup...) I guess iStat Pro and Disk Inventory X must just be reading in base-2, could that be it?
Do you still recommend booting from the SL DVD to repair the drive? Does everything sound like it's perfectly back to normal, so I can feel safe about making more backups and restoring to it should something horrible happen without finding out that there's something weird and messed up with the booting or something?

HP laptop says "no bootable device" for weeks at a time and then fixes itself

Hello,
I am a college student. I have an HP pavillion laptop that I boughtin 2009- I do not currently know the exact product name because the IT center of my school has it. It crashed in 2010 and was found to have come with a faulty hard drive, and the hard drive was replaced. Ever since then, once in a while it will get a blue screen (the same blue screen I got the first time it crashed) and then whenever I try to turn the computer on it says "No Bootable Device." It will give me this error message for days or weeks at a time, and then all of a sudden it will start working again without having lost any information.
I have brought it to the IT center at my school twice. The first time they gave it back and said there was nothing wrong with it. This time, I was very insistent that there was something wrong and explained the problem in detail. I got a call today and they told me that they ran tests on the hard drive, and it's working fine, and they cant do anything else. They also said they could try reformatting it if I bring in the discs that it came with, but my dad told me that means I will lose everything on my hard drive.
I'm hoping there will be a simple solution that I can do whenever I get this error message but I'm guessing there won't be. I apologize in advance because I really don't know much about computers so I may have trouble understanding computer jargon..
Thanks!

Without knowing the product involved it is hard to help. You are correct there is likely no magic bullet if you are getting "no bootable device" other than shutting it down and trying to boot again. A 2009 laptop is now 4 years old and that is about the expected life of a laptop although this one seems to have been snakebit from the start.
Ask the IT Center exactly how they tested the hard drive. I am suspecting you have one of the ill-fated dv6000 or dv9000 series models which have heat related issues and high failure rates, but won't know until you provide the model number.

No bootable device issue when installing Win 7 Pro 64 with OSX 10.8.3

Trying to install Win 7 Pro 64 on brand new iMac running 10.8.3.
Using external LaCie optical drive to read Win 7 OEM DVD installer.
Using Bootcamps Assistant, I can create the Windows partition but then when the iMac restarts to insatll Windows, I get a black screen with the message No Bootable device found.
Seems the iMac is not able to boot from the LaCie external drive.
Have tested the LaCie on both a mac and a PC and it works fine.
This iMac can see the drive and its contents in OSX but can't seem to boot to it to install Win 7.
How do I get a round this?
I have done dozens of dual boots using bootcamp but all with Macs that have built in optical drives. Have never had this much trouble.

I just got this working - finally!
My solution was to download the Win7 ISO file from microsoft and then use BootCamp Assistant to create a USB ISO. From there, I was able to boot to that "disk" and install Windows. I read a variety of posts some saying that you cannot use an external DVD drive, others saying that you could but it had to be an Apple SuperDrive. In any case, the ISO download worked and I would recommend that approach.

Installing Windows 7 on iMac via external superdrive resultes in "No bootable device-insert boot disck an dpress any key".

I previously had Windows 7 on my Mac, but removed it after returning from deployment because it had a virus that I could not remove. The only way to remove was to insert a CD/DVD with the anti-virus on, but in my absence, the optical drive was not cleaned and did not work. I had only been using partition for college, so I removed it.
Now, six months later I am trying to re-instal Windows, but after creating the partition and inserting the disk into the external Superdrive, when Bootcamp reboots I get "No bootable device -- insert boot disk and press any key". Nothing happens, I can't even type on the screen. I can reboot to Mac via the alt-option key fine, and I can see the drives, the Windows CD, etcetera, but nothing works. When I go back to Mac, Bootcamp won't work unless I delete the partition over from scratch, but I'm getting the same result.
Is the computer looking for the internal optical drive (which doesn't work, and can only be repaired by sending the whole thing back to Apple)? Is there a way to default to the external optical drive?
Thanks.

Bob, thanks. I misread the PDF (font on phones is difficult to see). Got it fixed now.

Get "no bootable device- insert boot disc and hit any key" error

Hp G72 Laptop, Windows 7 64 bit,
"no bootable device-insert boot disc and hit any key" (I have no boot disc.)
I was in the process of replacing the hard drive and the computer was starting the final phase after copying all files. When it restarted the first time, I got the message. I was getting this message randomly prior to replacing the hard drive and if I turned it off for 2 or 3 hours and turned back on I would not get the message. The reason for replacing the hard drive was a "Smart Disc " imminent failure error message.

Yes and yes. The final recovery disc had completed and it was moving to the next phase. It said the computer would restart several times during this phase and when it went to the first restart, the error message came up and I could proceed no further. I ctrl/alt/del and restarted, pressed escape to get the start-up menu but was lost at all the options. The information screen looked like the old hard drive info.

10.9.2 install Bootcamp win7 64bit iMac mid 2010 no bootable device - external superdrive, USB Stick

Hey all,
big problem here.
Trying to install Bootcamp on my iMac 27" mid 2010.
The thing is, during the installation, i get the "no bootable device" black screen, and i think i know why... but i need help.
System, a mid 2010 imac, 2TB HD ( Original) and an SSD Samsung 1TB at the Optical Drive SATA connection.
2TB HD is empty atm. OSX Installed on the SSD.
Bootcamp Assistant. Problem nr. 1.
He first did not want to let me create an USB drive. after hacking the assistat, deleting the "Pre" thing in the info.plist, that worked so far.
https://discussions.apple.com/thread/5479879?start=105&tstart=0 and several other postings got me so far.
Then when using the assistant, after choosing partition and so, when the iMac restarts, i get the "no bootable device" notice.
Read a lot, and it seems, that older iMacs, that originaly came with an internal superdrive only can install win 7 from that internal superdrive.
I have the problem, that i had it removed to put the SSD there.
So, when doing an EFI Boot, choosing the win USB Stick or the Win in my External Superdrive, - "no bootable...."
So i searched more. rEFIt should help. Installed, and all, doesnt work, same thing. As soon as i want to boot Win from the CD or Thumpdrive, doesnt work. :-(
In one of the many posts, someone wrote something about starting Shell in rEFIt first, etc... didnt work as well.
then i found this post:
http://www.andrewsavory.com/blog/2011/2156
sounded promissing. Somehow getting win installation files onto the Created Bootcamp partion with Virtual Mashine. But it didnt work for me.
The VW Fusion ware is different, and non of the steps he discribes works.
So how can i get it working.. it seems like it is somehow blocked to access something from the USB Ports.
Logicaly i would have to get the installation files onto a Internal drive. i Tried to create a partition and copy the Win 7 USB Thump using Disk Util Progeam onto a seperate, internal partition.. but he just does not what to do that... errormessages when trying to copy it, recreate the drive, etc.
So, i do have a 2TB internal HD, which i can use, an external superdrive, USB.Sticks. any gameplan?
And for Error-excluding: i have an original Win 7 64 bit CD, a burnd one and controled the Hash of the loaded ISO, which i downloaded for the USB-Stick.
Any help? pls!!!

Hi Sam, the Mini Optical may draw too much USB power.
Can you restore that .iso to the Flash Drive as a CD/DVD instead of an image file?

Why is Bootcamp is not working right on my MacBook Pro (No Bootable Device)?

      I am not a computer geek but I learned a lot through reading forums and other people’s experiences. I want to use Windows 64bit in order to work on an Architecture portfolio using AutoCAD, Revit, 3DS Max, Sketchup, Photoshop, and Illustrator. I use these programs at school and on a PC and love it. I want to use these programs at home but wasn’t confortable with the Mac version so I had Windows installed on Parallels but even after upgrading my RAM to 10GB my computer was quite slow so I rather work on my projects separate from my Mac side (also, would feel less distracted) and set up Windows on Bootcamp, but I’ve encountered some issues.
        I wasn’t planning on partitioning my hard drive until after updating to Mavericks. Then I noticed I did not have the option to create a Windows 7 install disk so I reprogrammed the info.plist for the option to appear. After following all three steps, the computer restarted with a black screen that read “No bootable device – insert boot disk and press any key”
-Pressing any key didn’t help so I restarted and held the alt/option key until the booting options popped up and only got
     -Macintosh HD
     -Recovery HD
-Did not get a Bootcamp boot option so I repartitioned the hard drive to a single volume and repeated several times and still the same thing
-I tried using Disk Utility to partition, but the results were the same
-I tried using a different Windows7.iso file and still the same
-I also tried a 2.0 and 3.0 USB thumb drive for the .iso file
-Bootcamp Partition shows up on my Finder window on the side tab under ‘Devices’ and shows up on Disk Utility, but not on Startup Disk and not when I start my computer and hold alt/option.
-I did not plug in the Windows Support Software at all (I read somewhere that said not to plug in until after Windows partition boots and installs, but didn’t even get to that point)
-Had no CD nor USB plugged in other than the flash drive that carried the .iso
-I read a comment that said to copy the files bootcamp made (WINISNSTALL) to the ‘root’ of the flash drive, but that I see they are already on the ‘root’ (unless I don’t know what root is?)
-I also tried reformatting the partition on Disk Utility from MS-DOS (FAT) to Windows FT Filesystem but fails every time
-I also made a backup, and restored the computer (took hours!) and repeated everything
-After trying almost everything, I still get the “No bootable device – insert boot disk and press any key” message.
When it gets to reformatting, I have no idea what I am doing, the only reason I am trying all these methods is because of what I read on other peoples success stories and comments, but its either my computer does not work, I am missing something, or I’m not geek enough.
-Just to let you know, the first .iso I had worked on Parallels but not for Bootcamp
-I don’t think this matters but I am trying to partition my 320GB hard drive at 70GB for the Windows side. The only thing I will be installing would be the architecture programs while my projects and files would be saved on an external hard drive.
-Computer is up to date at version 10.9.1
-MacBook is from Early 2011, 13-incher
-The only method I could think of that I did not try was using a DVD to create an .iso disk because most comments said USB gave the best results.
-Should I use my Hitachi 250GB External Hard Drive 2.0 instead of a USB Sandisk 16GB 3.0 and Verbatim 4GB 2.0
PLEASE HELP ME ANY ADVICE WOULD HELP!! And Happy Holidays!

Your post is incredibly hard to read, font is way to small.
If you used Boot Camp Assistant to create a partition to install Windows to you need a REAL Windows 7 or 8 install media and license key and you have to actually install Windows on your Mac. Boot camp is only for creating a partition to install Windows and starting the Windows install from REAL Windows install media.
That Windows install media has to be a DVD disc, if your Mac has a built in DVD drive (Apple does not allow Windows to be install any other way on Mac computers that originally come with a built in DVD drive), or from a USB stick with the actual Windows install files on it (Not an ISO of the Windows install files).
So the question is did you install Windows on your Mac? It doesn't look like it from the Option key boot and the list of available Boot Devices you posted.

Bootcamp "no bootable device" Option key not working

Ok recently rebuilt 2 older "Intel Core Duo" Mac Mini's with SSD drives. They work great and have been flying, however on one of them I wanted to setup BootCamp so that I could run Win7 Pro on it as well.
So here is what I did...
- When I first built the Mini's I used a bootable Firewire drive with Snow Leopard installed
- I had the drive divided into 2 partitions at first
- when I tried to install BootCamp error message kept telling me it needed only one part, so I finally made Primary OSX part one big part, then I was able to get BootCamp going
- I choose "I have Mac OSX Install disc" because "Download the Windows support software" would not work
- Next it created the BOOTCAMP part and told me to put Win OS disk in drive
- I put in an OEM Win 7 CD I borrowed from work, so I could see how it worked.
- When it rebooted, it Did not recognize CD and all screen said was choose Option 1 or 2, (neither option had any text, and the keyboard would not take any input)
- Tried numerous times to get back to OSX, used every boot option I could find online but none would work.. Also Mini would not give back CD for nothing
- Next I opened up Mini to get to CD, I had a friend that was able to get one out by opening up the actual dvd drive but I was trying to avoid that. So what I ended up doing was using a putty knife to keep CD from spinning on bootup. After about 10 to 15 seconds of the CD not spinning, it finally kicked it out for me. (YAY!!)
- New problem, now I have the "No Bootable Device - - Insert Boot Disk And Press Any Key"
- I have tried the following. Removing the drive and plugging in a Sata to USB cable so I can access it from other Mini
- I thought that if I deleted the BOOTCAMP part it would allow me to boot back to OSX, I tried renaming Part to what it was before, I have tried putting in a Formatted drive with no OS on it, I have tried installing the contents of a Win 7 OEM CD onto Formatted drive as a single FAT part.
Nothing Works, I am either stuck at the "No Bootable Device" screen, or if I turn on Firewire drive with Snow Leopard I get a blinking cursor that never shows any text.
At this point, I don't want BootCamp on that Mini anymore, I just want my working OSX, but I cant get anything to work and I'm afraid to stick a CD in the Mini for fear it wont give it back to me and I end up damaging it getting it out. I even created a CD with rEFIt on it, but after I formatted a totally different drive and the Mini is still expecting to finish what it start with BootCamp, it leads me to believe that there is some BIOS or data stored somewhere that is not on the harddrive. If so, could I pull the RAM, or push some sort of master Reset button some where?
I'm also thinking that I need a non mac USB keyboard, perhaps maybe there or know Aluminum Keyboard drives in the memory where the Mini is trying to finish the BootCamp install.
As a side note, I sure wish Apple would have designed the Mini to fail Safe not fail broken.
Please Help.
Randy

The Formatted test drive did not have Any OS on it. I just thought that since that was how I installed it originally, that it would work.
I put in SSD straight out of package, connected Firewire drive with SnowLeopard install, and it booted to it and asked me for to install to which drive, I choose SSD and it took off..
So what your saying is, do the same thing but hang SSD from broken Mini onto working Mini and boot up with same Firewire drive, and have it install OS back onto Broken SSD drive.
Assuming all of this works correctly, why would plugging it back into broken Mini work? Wont the Broken Mini still be looking for BootCamp to finish what it started? (just seems that way from what I've experienced so far)

No bootable device boot camp macbook pro retina 10.8.4

Hi,
I am reposting this under this community instead of under os x system software since it looks like there is no way to move posts to a different community. Anyway, just bought a brand new Macbook Pro with retina display running 10.8.4. I have always been a PC guy so I wanted to create a small Windows 7 Professional edition partition. I am using bootcamp to try and install it but I keep getting the above no bootable device black screen when boot camp restarts the mac to boot from the usb. My flash drive is a Kingston Data Traveler 16GB. The kingston does not come with any of its own software. It's completely blank. I have to use usb since I have no optical drive. These were the three different ways I have tried so far.
1). Using my older lenovo PC, I created an iso image of my windows 7 disc using one of lenovo's bundled software: power2go.
Transferred it to my mac with the kingston and then ran bootcamp. - Failed
2). Used the windows 7 USB/DVD tool. Now when trying to do this, the tool said that the iso I have is not valid. I searched around the net for this problem and resolved it using another tool. Now before actually using the tool to copy the iso to the stick I thought to myself maybe this problem is why bootcamp failed. So I transferred the 'fixed' iso and ran bootcamp again on it and still same result.
3). Actually use the win7 tool and copy the iso to the usb. Since I had already partitioned the drive I didn't go throught the boot camp assistant. I was going to install the support software later after I could confirm mac could boot from the usb. I restarted the mac with this usb stick plugged in and same result.
Now in all three steps I actually pressed and held the alt/option key upon reboot and in all three instances there was no 'Wininstall' drive that I could select to start the installer. All I see is the macHD and the recovery partition.
Doing some searching there were some threads that discussed modifying the plist (in the disk utility app I think) but to me that was only so bootcamp could add in the option to create an install disk via usb. Since that problem isn't there I didn't bother trying it. Maybe I am wrong? Any other suggestions?
Thanks in advance.

Update: A user responded to the other thread. So the usb flash device that I am using is 3.0 and looks like there can be problems with that one. So the proposed a solution is to get an external dvd drive and try to install it that way. Perhaps a usb 2.0 stick might work as well. In either case I'll have to buy one. Will update this once done.
The other alternative is to use windows through a VM.

Bootcamp "no bootable device" error while trying to install win7 on imac

Hello everyone,
I'm trying to install my original copy of windows 7 on my iMac 21,5 mid 2010 with mavericks as os.
This is what i do:
With my dvd of windows inserted in my cd/dvd reader I open bootcamp, i make the usb with drivers, i make the partition dedicated to windows and then the iMac restarts automaticcally.
When the iMac boots up a black screen (windowslike) appear saying : "no bootable device insert...etcetc and press any key"
First of all i'm using an external dvd reader because since i've upgraded to mavericks my superdrive stopped working (another big issue i've found out these days).
Then i've also tried making an usb bootable device....same black screen appeared.
I've been searching on the internet for days now without luck.
I believe i've tried everying but this funky situation keeps occourring.
I need to say that I installed windows on my iMac in the past and everything worked just fine, more then fine!
I need help please because i need windows on this machine due to working deadlines.
I'm desperate.
Help.

Kernal Data Inpage Error, No Bootable Device, Critical Process Died AGAIN! Please help!

I bought this S55-A5295 in July 2013. It started to have problems in April 2014. After 3 months of Critical Process Died, No Bootable Device, and having it shut down multiple times a day, I eventually convince service to take accept it because when I tried to do the recovery, the hard drive was missing partitions needed. (My $30 to ship, despite under warranty)
I received it back late June. The factory replaced the faulty screen (a different problem), but did not replace the hard drive. They supposedly "fixed" it, and added the needed partitions, should I need to do recovery again. I know that the partition was added because when I got it back, instead of being like new out of the box and ready to use, I was locked out because it was set to administrator and there was no option to access it, so I had to use the partitioned info. and do ANOTHER reset after getting it back from them. Not great service all around.
Now the laptop is out of warranty and I've started having problems again.
Sept. 16 -- I had a Kernal Data Inpage Error. The laptop made a horrible sound and shut down. At the time there was a Toshiba Canvio Slim II external drive attached.
Sept. 18 -- EFI\Microsoft\Boot\BCD 0xc00000bb the boot configuration data for your PC is missing or containing errors.
Sept. 19 -- Kernal Data Inpage Error. At this point I had removed the external drive, in case that was the problem. It wasn't letting me remove it earlier in the week. I didn't use it much over the next week.
Sept. 27 -- No Bootable Device.
Sept. 30 -- Kernal Data Inpage Error (volmgrx.sys)
Then Critical Process Died -- 3 different times
Then it restarted itself once without an error code.
Today, Oct. 1, I installed updates from Toshiba, including one fpr HDD and I performed maintenance. I tried to do the hard drive check, but the tabs in the instructions on the computer don't actually exist.
The directions: go to Computer, Properties, Tools tab (can't find it) , so no Error Checking and Check.
However, I did find, under Performance information and Tools my computer's performance rating. The Primary Hard Disk data transfer rate is 5.9.
So far it hasn't shut down today and hopefully the updates have fixed any issues, but I want to be prepared if they don't.
Are these errors coming from my laptop's hard drive? Is there a way for me to actually check that? Are the errors somehow connected to my TOSHIBA external drive? I haven't connected the external drive since the errors started happening, but i will need to use it again at some point, I just wanted to make sure the laptop was okay first.
Also, I am still running Windows 8. That's what they reset it to at the factory, and last time the issues seemed to correspond to me upgrading to 8.1, so I am wary to end up with a $600 paper weight again.
Please advise. Thanks!!

..went through the whole reset. ... ..do ANOTHER reset after getting it back from them
What can I say? The gold-standard test for a software problem is to restore the hard disk to its original out-of-the-box contents.
I'm a Windows specialist. Can't troubleshoot hardware.

No bootable device - Windows Vista

Hi there.
I've seen many posts with this question all over the internet, but I never got an answer, so I'm hoping someone here can help
me.
I turned off my computer last night and it was fine, but this morning when I turned it on the following message appeared:
"Intel UNDI, PXE-2.1 (build 082)
For Realtek RTL8101E/8102E PCI-E Ethernet Controller v1.07 (080320)
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM.
No bootable device -- insert boot disk and press any key"
When I press F2 to go to Setup, it says 'None' regarding the hard drive. The booting settings show 'HDD' in the first place.
Can you help me? Do I really need to replace the hard drive? How did my pc stop recognizing the hard drive overnight?
Thank you very much.

Error message on screen: No bootable device -- insert boot disk and press any key comes on

Error message comes on screen: No bootable device -- insert boot disk and press any key. What do I do?

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
If the above is not possible or failes, then replace your hard drive.
