Langsom computer

Hej udviklere!
M�ske ikke det mest passende forum, men Eksperten er absolut ikke gode venner med mig lige nu. Den virker overhovedet ikke. S� her kommer det.

Jeg har for et godt �r siden erhvervet mig en god pc, med gode specifikation (i7, DDR3, osv.)

Men p� den seneste er den blevet langsom i alt lige fra bootup til Autodesk
Inventor.

S� findes der noget software der kan forbedre pc'ens hastighed og ydeevne?
Gerne gratis, men billigt software kan ogs� g� an.

dual-boot USB-Stic

Hej.

Jeg arbejder som it-supporter, og bruger derfor meget af min tid p� at formatere, eller reparer computer for mine kunder, og bruger derfor tit Windows DVD/CD'er og andre former for utilities.

Jeg har ingen erfaring indenfor programmering, og har derfor brug for grundig hj�lp.

Mit sp�rgsm�l:
Da jeg bruger mange Windows DVD/CD'er, har jeg i l�nge g�et og haft tanker om at lave et USB-stik hvorp� jeg kan dual-boot og v�lge mellem de forskellige Windows installationer, og eventuelt ogs� have nogle af de utilities som ligger p� "Ultimate Boot DVD".

Er der nogen der m�ske kan give mig nogle hints eller fort�lle mig hvordan man kan lave s�danne USB-stik?

Multi-boot: Win7, Ubuntu 11.04 og Android

Sun, 29 May 2011 23:24:05 GMT

Okay..

Jeg fors�gte med google groups, men har endnu ikke rigtigt fundet en l�sning..

Det jeg fors�ger, er at l�gge et menu-punkt ind i min grub s� jeg kan boote Android.

Det er i engelsk.. har ikke lige overskud til at overs�tte. Sorry.

Her er hvad jeg har f�et derfra:

I installed Win7, then Ubuntu, then android,, but i didnt install windows boot menu,, i just made a normal installation, and ubuntu installed Grub boot menu.. but i was recommended not to use android boot menu, because it wouldnt recognize windows..

And i really like the ubuntu boot menu, and still want to use it..

All i want to is add android to the menu, but i cannot find a way to do that.

My entries should be right,, there is something wrong with the installation of Grub.. but i dont know exactly how to reinstall Grub..

Grub is not installed to a separate partition, but i think it is installed on the ubuntu partition.

In "GParted" my partitions look like this:

Kode

/dev/sda1 - NTFS - System Reserved
/dev/sda2 - NTFS
/dev/sda4 - FAT32 - Android
/dev/sda3 - extended
  /dev/sda5 - ext4
  /dev/sda6 - unknown

I found this folder "/boot/grub/" on my linux partition..
and think i have to do this: sudo grub-install /dev/sda5

But i want to be sure, before i do anything.

I was told to check this blog post

http://www.ceh-photo.de/blog/?p=357

And followed the guide...

I made this:

Kode

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry "Android-x86 2.2 (MDPI)" {
set root=(hd0,4)
linux /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=lenovox201 acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2 DATA= DPI=160
initrd /android-1.6-r2/initrd.img
}

menuentry "Android-x86 2.2 (HDPI)" {
set root=(hd0,4)
linux /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=lenovox201 acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2 DATA= DPI=240
initrd /android-1.6-r2/initrd.img
}

menuentry "Android-x86 2.2 (VESA)" {
set root=(hd0,4)
linux /android-1.6-r2/kernel quiet root=/dev/ram0   androidboot_hardware=lenovox201 acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2 DATA= vga=788
initrd /android-1.6-r2/initrd.img
}

menuentry "Android-x86 2.2 (Debug mode)" {
set root=(hd0,4)
linux /android-1.6-r2/kernel root=/dev/ram0 androidboot_hardware=lenovox201 acpi_sleep=s3_bios,s3_mode DEBUG=1  vga=788 SRC=/android-1.6-r2 DATA=
initrd /android-1.6-r2/initrd.img
}

But there is no any menu entry's showing up.

Now My "grub.cfg" file looks like this:
