computer laptop Windows 8 cannot find the boot device


I had a problem with my dell vostro laptop computer with windows 8 OS.

Today, when I try to boot my pc, I have an error like "no boot device found. If please restart the PC or insert the boot device.

Later, I tried to run diagnostics on start up, here I got an error like 2000-0142. The test failed.

But now I can't start my pc because pc says that "your PC has encountered an error.

I think that there is an error in the HARD drive.

Can someone help me please?


As I said it is a mistake to standard hard drive to Dell machines, who tells you that they do not have or go.

Once replace you a hard drive in this State.

Read this information from the Dell Community.

They are all the same error code 2000-0142 and they all need a replacement hard drive.


You cannot start Windows if you can't do a backup.

You can try this, but no warranty if:

Saving your files:

You can remove the hard drive and put it in a hard drive USB enclosure > plug it into another computer > and try to read and copy your data in this way.

Or, you can download Knoppix > make a bootdisk to > start your system with it (IF your material is all work) > and copy your data from the hard drive like that.


Your other option is to recovery specialists of data that are very, very expensive.

See you soon.

    Hey everybody,

    I was running Windows vista professional for more than 2 years yesterday, I formatted my hard drive and reinstalled vista prof. (entirely new, different CD key). Everything works very well excenp for one thing - I had saved some of the programs and files on my external hardrive before formatting my laptop. Now, when I try to access these files I get the following msg-"cannot find the specified device, path, or file." You don't have permission to access them. ".
    I am logged in as administrator.

    Help, please. I reallly need the files.

    Any help would be appreciated.

    1 right click on the file, then select Properties
    2. click on the Security tab
    3. click on change, in the name box, type "Everyone".
    4. in the boxes next to the permissions below, put 'Total control' for everyone
    5. click OK, and then close the dialog boxes
    6. try to copy the file that you just modified.

    If the works above, you must change the permissions on all the files you want to copy.  Normally, you can just highlight all the and follow the steps above to change the permissions on all files at the same time.

  • Computer laptop Windows 7 cannot print on PSC 2410, attached to the desktop of Windows XP on network home

    The subject little line about everything said.  I finally received the laptop to see the printer and went through Windows update to find our model of the printer, but when I print a test page nothing happens.  I tried setting up as a network printer, but could not find a driver (which he required).  Finally, I went through the local printer option to get as much as I did with her.  I also tried the XP desktop to add a printer driver for Windows 7 64-bit OS, but this option is not available... I was sharing the printer tab.

    It's very frustrating because I had no problem setting up my Vista laptop.

    Try the following: on the Windows 7 machine go devices and printers folder, add a printer, a local printer, create a Port, Local Port, \\Computername\Printername (use the name of the actual share of the computer and the printer), OK, then click Windows Update, and then select HP for the manufacturer and series HP PSC 2400 during the updating of the list.

  • Windows Vista cannot find the CD/DVD drive

    The problem: my computer does not find my CD/DVD drive, it is not listed in Device Manager as at all CD/DVD drive, it has power because it opens when I press the button, and when I put a CD, it does nothing.

    My computer: I have Windows Vista Home Premium, dv6700 Notebook, 32 bit, running on the System Pack 1. (I tried to update to the pack 2 system, but at some point, he is simply decided to AC turns off and when I booted up my laptop, he did a system restore and poof, System Pack 2 was gone, and I never re-installed.)
    What I tried: I tried the Fix It program here on Windows, and it has detected a problem (if I remember correctly, but had no trouble for him); I tried deleting the upper and lower filters (which I haven't really found, because the CD/DVD is NOT an option in my device manager); I tried setting my computer back to factory settings completely.
    Basically, I'm at a loss to know what to do to try to solve this problem. I don't remember how long this has happened (at the time, that my hard drive does not open even for me to put a CD) and I don't see what program could have caused it as appropriate. The only rider listed is listed under disk drives, and it's WDC WD2500BEVS - 60UST0 ATA Device (I don't know if cela help/questions in all). I do not have a disk; the laptop comes with Windows Vista and if she had a drive anyway, I didn't like this laptop was given to me by my father. I don't know what else to do to try to solve this problem. Someone please help.

    Sounds like something crashed. See if you can boot to the recovery (command-R on startup) Partition and select disk utility and then run First aid. If you cannot start the recovery partition, chances are that the player broke down.
