Generally speaking, installing an operating system will not require any changes to the BIOS, other than perhaps changing the boot order to launch the installation disc.
You can not delete partitions from BIOS. Boot from the operating system CD by pressing F12 as soon as it is powerd on and boot from cd/DVD. If you are talking about Flashing the BIOS then you can go to the dell website and download the BIOS for the computer and FLASH it from the operating system
if its pre-installed, you cant. if you want a better operating system pre-installed get a better computer ; a newer one. or another option. bye a new operating system and install it. hope this helps ;]
It is when your current Operating System and files are wiped from the main harddrive and a new copy of the operating system is installed. If backed up, you files can then be copied back into the new system, but programs will need to be installed again as well. This is usually done if hardware has (at least partially) failed, malware has damaged the system beyond repair, or for some other reason part of your system has been corrupted.
Vista, XP or whatever is installed on your comp. Windows 7 is the new one.
Windows 8.1 can be downloaded and installed on a Windows 7 PC, but Windows 8.1 is not an update it is a new operating system. This new operating system can be bought from Microsoft for $119.99.
ROM memory in a computer normally contains BIOS (Basic Input/Output System), which is the first program to run once a computer is switched on, before the operating system loads. It initializes and tests the system hardware. BIOS can be modified by flashing a new firmware, though it is not normally recommended.
On power-up. You need to tap the escape key to stop the operating system loading, and enter the BIOS set-up screen.
It is not at all important to do a defrag if you just installed an operating system. It is usefull when you have removed software or just before installing new software.
you can get a new operating system online.
There is no "bios" directory in windows (or, any other operating system). BIOS stands for "basic input output system", and is a very basic set of instructions for the hardware to initialize itself and prepare to load an Operating System. BIOS is almost always held in an EEPROM on the computer motherboard. Accessing and changing this EEPROM can only be done through special programs specifically designed to modify the BIOS. In most cases, PC BIOS is not directly readable by you - rather, you can update the contents of them by using a bios flash program. This program (usually supplied by your motherboard or computer maker) is run, and provided with a pre-made image file, which contains the entire new BIOS code to be loaded in. This update program is an ordinary program, and can be run from any location (directory) on your computer.
"ROM Basic" refers to the BASIC interpreter found in old IBM PCs. When the hard drive was not installed properly, you would be dropped into the BASIC interpreter instead. Most PC clones, including your laptop, do not include a BASIC interpreter. Make sure that you have installed the hard drive properly, and that you have installed an operating system on it. Otherwise, the laptop will not be able to boot.
Microsoft discourages computer manufacturers from selling equipment with older operating systems installed once a new OS becomes available. It is usually more financially attractive for the manufacturers to offer the new operating system as Microsoft may give them discounts for purchasing it, and perhaps take the discounts away from the older operating systems.
