Windows cannot start because the following file is missing or corrupt: vgaoem.fon (EN)

Few days ago my Windows XP Professional failed to start due to a power blackout and showed the following error:

Windows failed to start because the following file is missing or corrupt:
C:\WINDOWS\SYSTEM\vgaoem.fon

If for some reason this happens to you too, don't panic, the solution is very simple. Just make sure you have a Windows XP installation cd and follow these simple steps:

Setup your computer to boot from cd (do this from BIOS or press F12 or F11 to change the boot sequence; might be a good idea to check your motherboard manual first to see how to change the boot order). Insert your Windows XP installation cd and restart computer.
 
When the "Press any key to boot from cd..." appears, press any key to start computer from installation cd.

After the Welcome screen appears, press R to start Recovery console.

Choose the operating system and press enter. Type in the administrator password and hit enter or just hit enter if you don't have a password.

Type map and hit enter to see which letter is assigned to the cdrom device containing the installation CD.
Type the following command to copy and expand vgaoem.fon file (replace E : with the corresponding letter of your cd-rom drive. Do the same with C, replacing it with the corresponding letter of the partition where Windows is installed), then press enter):

expand E:\i386\vgaoem.fo_ C:\windows\system

Notice the underscore after "o" in "vgaoem.fo_".

A message confirming the operation will be displayed.

Type exit to reboot computer and remove the Windows installation cd. Now your Windows Xp should be fixed and start normally.

Windows cannot start because the following file is missing or corrupt: vgaoem.fon (RO)

Mesajul de eroare ce face titlul acestui articol, s-a intamplat sa imi apara dupa o pana de curent cand aveam calculatorul pornit. In cazul de fata fisierul cu erori este vgaoem.fon, insa aceasta eroare poate aparea si in cazul altor fisiere, cum de altfel mi s-a si intamplat.
Nu va speriati atunci cand observati ca Windows XP nu mai porneste dupa o pana de curent sau alte probleme cu tensiunea din prize (fluctuatii de tensiune). De obicei solutia este simpla, ca si in cazul acesta.
Pentru a rezolva problema asigurati-va ca aveti un CD de instalare de Windows XP si setati BIOS-ul sa booteze de pe CD (intrati in BIOS si modificati secventa de boot sau la pornirea calculatorului apasati F12 sau F11 in functie de placa de baza pe care o aveti).

Asadar, pasii sunt urmatorii:
Introduceti CD-ul in unitate si reporniti calculatorul, selectand apoi ca mediu de boot CD-ul (vezi mai sus), apoi la aparitia mesajului "Press any key to boot from CD", apasati orice tasta pentru a boota de pe CD.

Dupa ce apare interfata de instalare a Windows si  meniul cu optiuni apasati "R" pentru a intra in Recovery console.

Dupa ce s-a deschis interfata MS-DOS a consolei, selectati sistemul de operare si apoi introduceti parola de administrator (daca exista, daca nu, apasati enter).

Tastati map si apasati Enter pentru a putea vedea ce litera corespunde unitatii optice (ex. E:\Device\CDrom0).

Tastati urmatoarea comanda (inlocuiti CD_ROM drive cu litera corespunzatoare unitatii optice care contine cd-ul de instalare, iar drive reprezinta litera corespunzatoare partitiei pe care este instalat sistemul de operare, de obicei C) pentru a copia fisierul vgaoem.fon de pe cd-ul de instalare in directorul Windows:

expand CD-ROM drive:\i386\vgaoem.fo_ drive:\windows\system

Atentie: observati in comanda de mai sus prezenta caracterului underscore sau "liniuta jos" dupa litera "o" in "vgaoem.fo_"

Va aparea un mesaj de confirmare a operatiunii, dupa care tastati exit si apasati enter pentru a reporni calculatorul. Scoateti cd-ul de instalare al Windows si porniti normal calculatorul (daca e nevoie setati ca prim mediu de boot hard diskul). In acest moment, Windows XP ar trebui sa porneasca normal.
