Linux In Virtualbox

I am having problems with my Sony Vaio windows
it boots up saying (on a black screen, grey text):
==============================================
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.
Enter=Continue ESC=Exit
==========================================
No matter how many times i tried to restart and even tried F10 repeatedly or Alt-F10 I can't get to any other screen other than the above screen.

So I thought ah to hell with windows on this machine. I'll just install a linux distro because it's for my uncle all he really needs is internet and watch youtube videos/movies.

I have successfully burned and installed Fedora before on other machines using LiveCDs when they had CDs.

This time I tried to burn the DVD since it's it doesn't fit on the CD (I got my ISO from http://download.fedoraproject.org/pu...86_64-21-5.iso)
But when i inserted my DVD and restarted the same black screen appears.

So i have been looking for an older version of Fedora that fits on a CD (I am thinking maybe it'll boot from a CD, not sure though) but can't find any.

Any thoughts or solution to my problem?

Thanks in advance.

I have VirtualBox up and running on my headless Centos 6 machine, am using http://sourceforge.net/projects/phpvirtualbox/ as a GUI, and created a virtual machine and installed Windows 7 on it.

I can access it using the VirtualBox console (via phpvirtualbox interface), however, only can see part of the screen and the mouse doesn't work properly. I can also access it using Windows Remote Desktop Connection using IP 192.168.1.200:9000 (why port 9000?), but again the mouse doesn't work.

I have the following ext packs installed on the server.

Do I need additional extensions to better interact with the guest? How are they installed? Thank you

Before i start id like to say im a total newb to linux.. Used windows for years but I'm not tech minded, my old pc run slow so i bought an ipad! Then was given a linux pc but a good friend about 4-5 years after buying an ipad.


Brief history
A friend of mine the other day gave me a pc he had lying around unused but dusty and had linux installed. i got it home and it worked perfect but no sound, messages him and i was told by a him to locate the "analog output" click that in settings and make sound run through it, all i could find was dummy output ( i think its called ), i researched it and found its because it was bugged so to sort it out i needed to uninstall and reinstall so i followed some guys code and did that.. It said the install was successful in the control panel type thing. but on restart i get a blank screen.. Like my monitor isn't working! " i used this method http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ no sure if links are allowed but i used this guys method to try and get my sound back and ended up with a blank screen after restart.

I get to the grub menu ( think its called )

I have found many post relating to blank screen but non are like the picture i posted or talk really in death tech talk which i don't understand.. I think in the grub menu i need to change something but I'm confused

I believe its when you reinstall stuff that it makes the monitor not work?? Could this be the case?? If so can you help??

Ps sorry if i posted in wrong section i am a total newb so please forgive me

And no in death tech talk, try keep it simple

Thanks commando.

Ps if you want me to explain things further please say. I'm not computer literate sorry but i will do my best.

hi guys,

i have virtualbox running on centos 7
i want to install another centos7 vm
i googled and found a few sites that show setup
but none show your initial setup in virtualbox
when i want to create a new vm i am offered:
linux 2.2
linux 2.4 (32 bit)
etc etc

all look 32bit...i thought centos7 was 64bit...or is it just emulated?
the only logical choice i can see is either:
red hat (32 bit)
or linux 2.6 / 3.x (32 bit)

i know its only a vm and i can experiment without breaking things (only the vm install) but i have a bit of a time restraint...

I installed Linux Mint but I can't see the taskbar to open menus,firefox or anything. When I hover my mouse in the bottom right corner the date pops up, so I think everything is there but I just can't see or click on anything. The only icons on my desktop are the Home and computer icons and they are barely on the screen but still visible. I'm hoping there is a way to adjust the screen ratio to show the whole screen. Also on web pages the "close tab x" is off the screen and out of range for my mouse to click but I was able to drag the page down to get to it.
I was able to make the taskbar icons larger, now I can see the tops of the icons so I at least know they are there.

Hello everyone from stackexchange,

I am a total Linux newbie, and for a short school task I have to perform the following action in Linux OpenWRT running in my virtualbox. I have tried multiple commands and googled a lot but I can't get it working. If someone could help me out on what to do, that would be awesome. I have looked through the manuals too but it doesnt seem to work.

Many thanks.

Hi all,

I'm not quite a newbie having been using Linux for around a year now and think I know some of the basics at least. In the main it does what I want, some things better than they ever did on Window while some things frustratingly more awkward!

I have a load of music files that I'd like to search through and transfer some to the external sd card of my android phone. This was something that was a doddle during my Windows days but seems unbelievably difficult now. Back then I used a media player I loved, Mediamonkey, and could simply drag and drop whichever tracks I wanted, or right click and move to a device that way. Sadly this doesn't work too well with WINE though so is fine on XP through Virtualbox, apart from a lack of USB function.

I'm using Linux Mint 17.1 with a KDE desktop.

When I plug my phone into a USB port, it is recognised straight away as an android phone and I can navigate around it with no problems in Dolphin. I could look for each individual file and transfer them that way but with around 30,000 mp3s the task would take quite some time!

None of the media players I've tried so far recognise the phone or the storage on it.

I've installed Windows XP on Virtualbox and have Mediamonkey on there with all my audio files. I can't seem to get Virtualbox to recognise any USB devices so I can't transfer files that way either.

I find it annoying that, in effect, Android is a variety of Linux yet connectivity between the two is so complicated. Airdroid has been the best way that I've found but that's not an option.

I've been trying for 4 hours now and have got nowhere. If anyone can help I'd be grateful Thanks

Hi there everybody,

I am getting really frustrated on a far to trivial problem. I am running ubuntu in virtual box on a windows 7 64bit machine. By default the screen has a resolution of 640x480 and thus only shows the upper left corner of the actual screen, meaning I can't see the entire screen. I was able to figure out, that I have to install guest additions but as soon as I go to devices -> install guest additions I get an error, that the medium couldn't be placed into the drive. It further asks me whether I want to force it to be mounted but if I say "yes" nothing else happens.

Any chance there is a simple way to solve this problem or is this really such a complicated issue?

Furthermore I would prevent linux from going into standby. Actually the settings say, that it will never go to suspend but it does so after it wasn't used for approx=. 5minutes or so.

Thank you guys very much for helping me getting rid of my newbeness :P

Hi everyone,

I tried to install Elementary Freya and everything was good, though suddenly while using my laptop I get a black screen. I cannot use the mouse nor the keyboard. When I press the power button, to put the computer in sleep mode, and the open it again, I can see the desktop but cannot do anything.
I tried to use Mint 17.1 and then reinstalled Elementary again but I keep getting the same problem.
I use Linux next to windows 8.1

Thanks in advance, I would appreciate any help
