If you are getting default boot device missing it may be due to failing hard drive or misconfigured boot options.
First check boot options.
If you are on a dell computer boot options may be reached by pressing the F12 key during the computers boot up.
If this is a non-dell computer it may show another key during the initial power on should say something like F12 to enter setup "F12 being a different key"

Other keys to try may include F2, ESC, F10, F11, some systems you may have to hold down "Shift + F11"
Once in the Setup screen you should see "Boot" or "Boot Options" at the top, use the Arrow keys to navigate to "Boot"
Make sure first boot device is set to cd/dvd
Second boot device should be hard drive
If this is correct press ESC and close without saving (options will be listed on the screen when you press Escape)

Generally this error is caused by hard drive failure, or a disk left in the drive (floppy, cd / dvd, or usb flash drive plugged in during boot)

You may need to seek physical help if you think the hard drive is at fault. You want to get the data recovered form your drive as soon as possible and refrain from any attempts to use the hard drive as this will lead to further damage.

Good day Ken Markham
If your "Default Boot Device" is your hard drive and it is missing, then your machine will not start, you may need to have a technical person look on your machine for you.

Windows 10 is the default and will be looking for a EFI file that is probably not set up on your old hdd. Change the format of the old hdd to accommodate the new type of boot file.

My packard bell is saying that default boot device is missing or failed, insert recovery media and hit any key


If you are using an operating system with a start disk, insert the start disk and reboot. You will then have to recover the software installation.

If you have your OS CD, you can start the computer using it, and then repair the software installation from it.

My boot devices are disabled


Hi

Normally for Pcs and laptops the booting devices can be found in the CMOS/BIOS settings, when you start up the pc/laptop you normally press esc f1 f2 etc, this allows the user to enter into the CMOS/BIOS setting.

Under the Boot tab you will see all the devices you boot from they will be enable/on or disabled/off check them to see which devices are on and off.

The last tab has a load default option if you select it and exit and save these changes it will automatically enable all the default devices in order.

Your pc/laptop should boot up normally now

Cheers

Getting the following error on boot up right after the ibm splash screen: ERROR Resource conflict - PCI Serial Bus Controller in slot 7 Bus:15, Device::00, Function:01


If it is not making it to Windows at all...Generally occurs when two devices are using the same IRQ or memory allocation. This can sometimes be set in BIOS depending on the manufacturer etc. I would start by going in BIOS and restoring the default settings. There should be a menu item in BIOS usually something like "Restore Default".
If it is making it to windows then you probably just have a missing or corrupt driver. Generally this would fall under a chipset driver which can be downloaded for free from hp's site. You can also download and run Everest or SIW to properly id the device in question.

Comment back with for findings results or for more assistance.

No sound at all


1) Go to: Start > Settings > Control Panel > Sounds, Speech, and Audio Devices > Audio tab 2) Check what's under "Sound playback: Default device" and "Sound recording: Default device". It these fields are grey and non-clickable, then most probably the audio card driver is missing or less probably the audio card itself is broken. 3A) If you have an original CD of your computer, motherboard, or audio card, insert the CD and install the driver from it. 3B) Or alternatively insert the CD and go to: Start > Settings > Control Panel > Performance and Maintenance > System > Hardware > Device Manager, find any unidentified device in the list, or expand the "Sound, video and game controllers" branch, identify the Audio card > Right click > Update driver... > Install the software automatically > Next 3C) Or alternatively download and install a free driver updater software, e.g. http://www.innovative-sol.com/drivermax/index.htm - let it scan and update all your missing drivers. P.S. These steps mentioned above are for Windows XP, but will be quite similar on other Windows versions, too.
If you tell me your laptop's model name, I could find its website where you can download audio drivers. For example if you have HP laptop, go to www.hp.com and enter your laptop's model number and look for driver downloads offered.

Missing NTLDR message, cd does not start ,have no floppy, this is a 503gr. F8 does display but does not continue to selected item, get black screen. Does a processor cause this failure?? Have original...


Your CD is not starting as it is not configured for first boot device. I am not sure on which function should be used to get to Boot Menu however you may want to try using either F2 or F12. Then its all about changing the Boot device fromHard Drive to CD. Once Changed follow the steps mentioned below,

  • Insert the Windows XP CD-ROM into the CD drive, and then restart the computer.
  • Click to select any options that are required to start the computer from the CD drive if you are prompted.
  • When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
  • Press 1 (One) to select windows XP and then hit enter.
  • When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
  • At the command prompt, start typing

COPY D:\i386\ntldr C:\ (Considering that D is your CD Rom Drive)
COPY D:\i386\ntdetect C:\ (a file that may also be missing)


Then rebuild the boot configuration boot.ini file by
Attrib -H -R -S C:\boot.ini (if not found skip the next line)
DEL C:\boot.ini
BootCfg /Rebuild


Once all these steps are completed make to change the boot device to hard drive from CD rom.
